The 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.
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.
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.
