Using an off-grid solar calculator to determine costs involves a little bit more data entry because your system will also need a charge controller, such as a 3000-watt inverter. These inverters convert the direct current (DC) energy absorbed by your small solar panel kits into alternating current (AC) so that you can use it to power your
Lithium-ion tends to operate at a better efficiency in winter. Assuming you are using lead-acid batteries in your off-grid PV system you will need to multiply your battery capacity by 1.59%. 11,176Wh * 1.59 = 17,769Wh (lead-acid) If you use lithium-ion batteries in your build, multiply your required capacity by 1.2.
Solar panels (kW) = Total annual energy use (kWh) / Solar energy per kW of panels. 10,500 / 1,200 = 8.75 kW of solar panels. To find out how many solar panels that is we have to divide by the size of each PV module. The solar panels we currently sell are 295 Watt each, and 295 Watt equals 0.295 kW ("kilo" just means thousand).
Off-grid solar systems are not the same as grid-tie solar systems. With an off-grid system, you are entirely independent of the grid and 100% responsible for your power needs. You won''t be able to harness extra electricity from the utility company. Learn more about off-grid vs. grid-tie systems.
