    Are cheap solar panels worth it?

    Overall, cheap solar panels are worth it if you can't afford to pay for premium panels. Switching to solar will always save you money, but cheaper panels will typically save you less money than more expensive ones due to their lower efficiency and higher failure rates.

    Which solar panels should I buy?

    Ideally, you want to use the highest efficiency panels you can afford. According to the National Renewable Energy Laboratory (NREL), most solar panels have efficiency ratings between 16% and 22%. The top-quality, high-efficiency panels cost the most. If you need cheap solar panels, look for high-quality panels that fall within the 17% to 19% range.

    How do I choose the most affordable solar panels?

    The most affordable solar panels for you will likely be a combination of those attributes, rather than the actual number on the price tag. An excellent place to start looking for the best deal is to start with inexpensive solar panels and work your way through the numerous decisions you'll eventually make when choosing your system.
