Please enter the size of the proposed solar installation in watts (watts DC).
Typically, the capacity of your solar energy system to produce electricity is described in terms of Direct Current (DC), but you may also see it listed in Alternating Current (AC). The AC size of your solar energy system will always be larger than the DC system size, as the solar modules produce DC power and then utilize inverter(s) to convert it to AC, which is what our home electrical appliances use. This process results in some losses. Learn more about the differences between AC and DC power.
You can calculate the DC size of the system yourself by multiplying the number of panels by the panel wattage (located on the modules themselves, or on the spec sheet), e.g., 20 panels x 320 watts each = 6,400 watts DC. Please note that if you’re receiving proposals from solar companies, the size may be provided in kilowatts (kW) or megawatts (MW). There are many conversion calculators available online.
