During the initial survey, the installer will check the feasibility, taking into account:the available space required for the installation of the modules (for every 1,000 W of installed power, about 3-4 photovoltaic modules are necessary)the correct exposure and incline of the surface, which must be facing southwards, southeast or southwest. The incline should be between 10° and 35°the absence of any obstacles that could create shade. [pdf]

Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW) system to adequately power their home, which costs $28,241 in 2025. That price effectively drops to $19,873 after considering the full federal solar tax credit. [pdf]
