An off grid solar system provides an alternative to traditional energy sources, offering energy independence and sustainability. By maximizing the sun's energy, this system presents an opportunity for eco-friendly living, even in areas where conventional power grids are unavailable.
In order to completely go off the grid enough electricity needs to be generated by either photovoltaic solar panels or wind turbines to cover their electrical requirements. Two different simulation programs, HOMER and PVSUN3, were used in order to determine the required size of the solar collector array and components.
Off-grid costs in range $0.2–1.4/kWh; grid extension < $0.1/kWh to > $8/kWh. Solar PV off-grid emissions range 50–130 gCO 2-eq /kWh, grid ~0 to >1,000 gCO 2-eq /kWh. Studies differ in cost methodology used, and lack wider environmental analysis. Methods integrating cost and environment impact required for holistic comparisons.
Off-grid solar system design calculation involves determining your energy needs, including adding up watt-hours per day of all the appliances and devices you plan to power. Variables such as peak sun hours, the efficiency of your panels, and power storage in batteries also factor in.
When it comes to how to design an off grid solar system, knowing your location’s solar insolation — the amount of solar radiation energy received on a given surface area in a given time — is key. This factor determines the number of solar panels and the size of the system you will need.
For the purpose of this review, grid electricity access refers to conventional centralised grid-extension systems typically powered by fossil-fuels and off-grid refers to decentralised solutions including stand-alone and mini-grid technologies powered mainly by renewables such as solar PV and batteries.
