Setting Your Expectations Correctly with Cheap Solar Lights

Hoont-Outdoor-Solar-Step-LightBefore rushing out to the nearest garden center or lighting store to add a set of cheap solar lights to your household it is best to consider the many options you have with these items, to avoid being let down by getting a set that doesn’t do what you had hoped.

It is important to bear in mind the limitations with these lights and not believe all the hype and buzz surrounding them – though of course there are very good reasons for being excited by the possibilities that solar lighting brings to the home, as you will see later.

Firstly though, consider what you will be asking your purchase to do. If you are buying a couple of small, cheap rock lights and are expecting to place them on your deck to light up the whole area when you have a party then you will be disappointed. They are designed only as accent lighting to be placed in a flower bed or light up around a hazard like a pond for a few hours during the evening. They normally have a small solar panel, a small battery and an LED bulb that processes the sun’s energy, stores it and releases it – as most solar outdoor lights do – but they are certainly not designed to produce strong lighting throughout early and late evening and into the night.

In this situation you will probably need to “up” your budget and go for some post lights and deck lights that you will install at regular intervals around your decking, providing both mood lighting and safety lighting that will illuminate step areas or other hazards. In other situations that require task or spot lighting the cost per unit will be higher still as you will need a light that uses a larger panel and multiple LEDs to provide adequate illumination. So cheap is not always the way to go with these lights.

Now we have covered the main downside that people experience with outdoor solar lights, let’s take a quick look at all the advantages of these units over electrical lights, before giving you a couple of tips how you can save money when purchasing them.

Firstly they use zero electricity so any cost differential between the outlay for these lights and that for electric lights is paid back over time. This makes them more environmentally friendly than electric lights, of course. Also, they have virtually no maintenance required to keep them running – there’s not even an on/off switch in most cases and they will turn themselves on as the light starts to fail.

Being easy to install – pathway lights are often pre-mounted on spikes that are driven into the ground – also means that if you buy a large set of units it doesn’t involve much work to get them all set up, unlike electric lighting which involves a qualified electrician to wire everything up and hide the cabling.

Buying solar lights in sets is a good money-saving idea. Some manufacturers like Westinghouse will package their lights in 6, 12 or even 24 lights so that you can choose a set large enough for the job at hand and place at regular intervals around your property – doing this will mean that the work you ask of each light will be less, as it will be spread out amongst more units. They are usually quite attractive designs too, so having lots of lights adds to the overall ambiance of your garden, yard or driveway area.

Of course another way to save some money when buying solar landscape lights is to get them online. Garden centers are a good idea to get a look and feel for how they work, but you will find cheaper prices available at the many specialist solar lighting web sites. Choosing one with a variety of brands, images, clear specifications and product information, a good ordering process, secure payment and a proven delivery process will give you the peace of mind to order online.

How to Change A Refrigerator Water Filter

replace-a-filterIf you haven’t changed a refrigerator water filter on your refrigerator, you may think it may be difficult. The fact is that changing one filter on a newer refrigerator is much easier and quicker. Generally, most refrigerator water filters can shut off automatically, if you unscrew it from the refrigerator. This design is very great. However, if the filter you have is not attached to appliances (e.g. a secondary filter), you need to shut the water off first and then to change it.

How to buy a replacement filter?

  • Buy it on local store – If you know the brand and the specific model of your fridge, you can unscrew the filter and take it to a local home improvement or hardware to buy one. However, you may not find the right filter because these stores may not sell the filter you plan to buy.
  • Buy It on line – it is highly recommended to buy a replacement filter on line. Of course, you need to know the brand and model of your refrigerator. You can buy it on line from many online retailers, like Amazon. They usually come in 2 or 3 packs and this can help you save money.

Twist on filters

Generally,twist on refrigerator water filters are located in the front, back or inside of the fridge. Different models may be different. First, you need to change a twist. This is so easy – just turn the refrigerator filter a 1/4 turn counterclockwise, and then pull it out of its housing directly. Don’t discard the knob which is able to be used on the new replacement filter. The reinstallation is also very easy. Put the knob on the new filter and push the water filter into its housing, and then turn it a 1/4 turn clockwise in order to lock it into its position. The process is just the reverse process of changing a twist.

Once you have finished the reinstallation, you’d better throw away 1 or 2 gallon of water or discard the first batch or 2 of ice in order to get rid of the carbon residue which is left behind by a new filter.

Make sure to dispense and throw away a gallon or two of water or discard at least the first batch or two of ice to get rid of the carbon residue left behind by a new filter.

Push in filters

This type of filters can be found in the front, in the bottom grille, in the top towards the back or inside the refrigerator. If you don’t know where it is, the product specification may have marked the location. The installation is much easier than a twist on filter. There is a button and just push it to release the old filter and then pull the old one out. And then you need to do is to take off the cap and push it onto the new replacement water filter. The last step is to push the new one with the cap in to lock into position. Before starting to use it, you need to dispense or discard 1 or 2 gallons of water or throw away 1 batch or 2 of ice, which can get rid of the residue left behind by a new filter.

Watts-543700 3-Stage-Filter

When do you Change the Water Filter?

Watts-543700 3-Stage-FilterIf you have a water filter, there is a question you should pay attention to – “When do you change the water filter”. This question is very important, because once the filters cease to be effective, the filtered water will be not pure as it used to be. Therefore, we should know when to change them before they lose their efficiency.

However, this question depends on several factors. Generally, water filters have their estimated life span that is measured in gallons of water. However, the estimated life cycle is only a guideline supposing you use filtered water on average water use. Therefore, it is not a good indicator to tell you when you need to change them, because every household uses a different amount of water every day. In the following, I will list some factors that may affect the life of your water filters:

Factors affect the life of your water filter:

  • The overall water condition: how many contaminants are in the water and how much do you want to filter every day.
  • If the water is very hard (hard water contains more minerals), the filters may be clogged by the building up scale.
  • How much filtered water do you consume every day, more than the average use?
  • If a filter is clogged or cannot filter out particles and contaminants, it become useless and ineffective. You have to replace it.

When to change?

  • If you detect an odor in the filtered water, this means your filters cannot work.
  • Filtered water tastes unpleasant.
  • The water pressure from the faucet becomes lower and lower gradually.
  • Filters are seemed very dirty with clear containers.
  • You have exceeded its life span that manufacturers recommended.

In order to ensure the effectiveness of your water filters, replace them on time is very important, ensuring that you always have clean filtered water to consume. A back-up replacement filter is essential for convenient change-outs. Different models use different filters that are sold by brand. You need to buy filters as same as your previous one.

Generally, if you have installed a reverse osmosis system, it is recommended to change its filters every 6 months to 1 year. Many models have an indicator that can remind you when to change them. Many faucet water filters may also have an indicator and you need to change its filer every 3 to 6 months.


What are Swimming Pool Solar Panels

Solar-Pool-Panel-SystemIf you want to use your swimming pool anytime or just extend the using time of it in a year, the first problem is that the water is too cold to swim. Therefore, installing solar panels to heat the water in your pool becomes meaningful, because compared with using a pool heater powered by gas, solar panels heat your pool without any energy from the grid needed and any greenhouse gas emissions. You may think power heating solar systems are expensive, but the fact is that they are not as expensive as you might think. In this post, we will talk about how they work and why you need them.

How Swimming Pool Solar Panels Work

Swimming pool solar panels are not solar photovoltaic panels that we use to power our home or charge batteries. They work differently. They have a sensor to regulate the temperature which you set according to your preference. A pump is used to filter the water and then water is sent by the pump through the solar collectors. When water travels through the solar collector array, it is heated by the sun. Warm water is led back to your swimming pool.

Types of Panels

Although there are numerous different models of pool solar panels, there are only 2 main types – Unglazed and Glazed.

  1. Unglazed – This type is made of heavy plastic and rubber. It is recommended to use it above freezing temperatures for better sufficient.
  2. Glazed – Its tubing is made of copper and its aluminum plate has a tempered glass covering. Therefore, it is more efficient than unglazed models and you can use it all year around.

Before choosing one, you should know how many panels you should install. There is a solar pool calculator to help you to calculate.

The Essentiality of Pool Covers

The swimming pool has a large surface, so the heat can escape easily if there are no pool covers. Pool covers are very important to keep the heat. It is highly recommended to keep one in place when you are not swimming in your swimming pool. This is especially very important at night. If you don’t use one, this is like pouring warm water into cold water in the winter.

Cost and Maintenance

There are many factors that may determine the cost of your pool solar panels, like the size of the pool, your geographic location and the orientation. Generally, it is estimated that investing in such a system may cost you about $3000 to $4000 and you can recoup the investment from several years to 7 years. The federal government or some states government may offer tax incentives, if you invest in solar panels, which can reduce up to 30% of the initial cost.

Generally, such a pool heating system can last for 15-20 years. In the first less than 7 years is the payback period, and from then on, the operation costs are almost none and they only need very low maintenance. If you don’t use them in winters, you should shut them off and keep them dry to avoid any damage from freezing in cold winters.


Some Solar Power Facts You Should Know

solar-roofIf you are planning to add some solar panel kits on your roof so that you can get green energy to use, firstly some basic solar power facts should be known. Due to solar panels’ self-sufficient feature, installing solar panel kits on your roof is helpful to reduce your energy bill and reduce your carbon footprint, too.

  • The term of solar energy means energy from the sun. We can use some devices to harness the energy of the sun. For example, we use solar panels to convert sunlight into electricity and we use solar tubes to heat water directly. In a word, solar energy can be a resource to power our home.
  • In 1876, William Adams discovered solar cells that make up of solar panels.
  • Similar to hydropower and wind power, solar power is also one of the cleanest energies and it is also a renewable energy resource.
  • Solar energy can be widely used to power our home, like heating water, heating our swimming pools, heating our home, charging batteries, powering many appliances(like solar fans), power outdoor landscape lights and RVs, etc.
  • Solar panels are made up of Photovoltaic panels (PVs for short) which are devices or equipment used to convert solar energy into electricity. Converting efficiency is about 15%. Although it seems very low, it is known that green plants are only 3% efficient at photosynthesis.
  • A solar power system can be separated from or connected into the grid. The term of net metering means you can connect your solar power system into the grid, so that you can sell your excessive electricity to the utility company. This can reduce your energy bill but get some money back from the electric company.
  • Similar to electric power, solar energy is also measured in KWH (kilowatt-hours).
  • Rechargeable batteries are essential for a solar power system, because they can store electricity generated by the solar panels, making it possible to use electricity at night.
  • You can try your best to use solar energy. For example, if your window is designed to orient the east or west, you can open your window to capture sunlight so warm your room. This is called as a passive solar design strategy.
  • If you have installed solar systems in your room, you may be qualified for tax credits offered by Federal and state which can reduce your initial cost.
  • Solar panels are durable to use and feature low maintenance. They can last over 20 to 30 years and warranties are also equal to the length of the time.
  • Solar panels can be mounted on the roof of your house and on a pole in the yard. Mostly, the roof is an ideal place.

Although investing in a solar power system is costly, it has many benefits in the long run. The solar power facts above can help you make a wise decision whether you really need such a system or not.


Advantages and Disadvantages of Solar Power for Home Use

SolarPowerSystemsThe most popular or common type of solar system for home use is the solar photovoltaic panel which is a device to convert sunlight into electric power. Solar panels are installed on the roof of a house and angled to mostly absorb the sunlight.

Top 10 Solar Energy Uses for Home

If you have decided to invest in installing your own solar power system in your house, it is recommended to ask a qualified solar professional for some help. You can tell him/her your specific requirements and situation, which can make your later investment value, or it is just a waste of money. Every coin has two sides and just remember their benefits and drawbacks in the following.


Self-sufficient – Solar panels will absorb the sunlight to convert into electricity which can be used to power your home’s electrical system or electrical appliances and lights in our house separately. Therefore, solar energy is a free energy. Solar panels make your solar home system self-sufficient. What’s more, if you have excess electric power generated by your solar panels, you even can make your solar power system set up for net metering so that the excess electricity can be sold to the electric company in the form of cash or a credit. As the decreasing cost of solar panels, you can completely rely on your solar power system without any power from the grid needed.

Reusable and clean energy –The process of photovoltaic conversion doesn’t produce any harmful emissions, making the solar energy very clean. And solar energy is reusable. The more this type of energy we use, the less carbon footprint our home produces.

Installation incentives – In order to encourage the use of renewable energies, Federal, state or local jurisdictions may offer tax breaks, discounts, grants and rebates for the installation. Therefore, this can reduce your cost.

Reduced dependency – Once you have installed a solar power system, this means the less electric power from the grid is needed. You become independent on the electric power from the grid. If you live in an area with frequent power shortages and blackouts.

Best Solar water heater for home use


High initial cost – Even if the Federal, state or local jurisdictions may provide you with multiple incentives, a home solar power system may cost you plenty of money – tens of thousands of dollars. Even smaller solar panels you buy are also costly. The whole cost depends on many factors, like its location, purpose, size, the goals of the householder, the situation of your home, and the amount of work which is needed to prepare. In a world, a solar power system is an investment

Not so Reliable – The system relies on the sunlight and the sunlight isn’t available for 24 hours per day or rainy, cloudy and snowy weather may cause weak sunlight which will influence the solar panels’ converting efficiency. What’s worse, some tall buildings or trees may shade your roof and the panels cannot receive sunlight all the time during the day. If the outdoor temperature is very high, this can also reduce the system’s efficiency.

Site Preparation – If you don’t have installed any solar power system before, the installing cost may be lower than you want to retrofit an old one. This because such a retrofit is more complicated than you think it should be. You may need to reconfiguring your house’s electric system, or you may need to upgrade, alter your home’s infrastructure systems. This will happen especially on the roof where your old solar panels were installed.

High Maintenance Cost – To keep your system working efficiently all the time, you need to do regular cleaning job by your hands. Solar PV panels need you to clean it on a regular basis. If there is a storm, you may feel worried about your solar system on the roof. Or you may need to arrange for a professional to repair any damage as soon as possible.
