When selecting solar panels, don't just go by price. Panels can vary by size, wattage, brand, warranty, performance and materials. Because of this, you should thoroughly research all the solar panels and select the highest quality one rather than the cheapest one. Purchase the highest quality panels that your budget will allow.
Remember that solar energy can do more than just power your lights. They can provide heat and warm up your water, too. Solar panels can make a significant impact in your overall energy bill. You don't want to be overpaying the power company.
Get the records from your energy company on how much energy you have used in the last five years. You can then use this information to figure out exactly how much power you will need solar energy to provide for you home. Having the past five years is important so that you can see that some years you will need more energy than others.
