A 3kW solar panel system will require less than 300 square feet of space on your rooftop.
Southern-facing roofs are ideal, and keep in mind that the actual square footage required will depend on the wattage, or efficiency, and the dimensions of the panels you install.
High efficiency solar panels will create more energy in a smaller area. So if you do not have about 300 square feet of roof space to spare, higher efficiency panels can help you utilize the space you have for a 3kW solar array.
A 3kW system will produce about 260 - 415 kWhs of electricity a month, meaning the amount of energy produced ranges from 3,120 - 4,980 kWhs a year.
Being that the average home’s monthly electricity usage is 893 kWh, a 3kW system might not be enough to eliminate your utility bill entirely. 3kW systems generally just help offset electricity usage and will not cover the entire electricity bill.
Anyway, the amount of sunlight your home state gets also determines the amount of solar panels you will need.
How to choose one suitable solar off grid system?
1, confirm the inverter voltage and inverter power based on your loads
2, confirm if the system is totally off grid or with grid/generator as backup
3, confirm solar panel power based on your daily load conumption and solar irradiance figure
4, confirm battery type and battery backup hours
The 3kw off grid solar system is usually for home use where there is no grid or grid is unstable. It can supply power to normal home loads such as washing machine, LED lights, fan, air conditioner. Inverter power: 3kW AC output voltage: AC110V/120V Battery voltage: DC24V or DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 5kw off grid solar power system is suitable for a place where is no grid network or grid power is not stable. It can be described solar storage system with utility backup power, or grid-tied solar system with extra battery storage(no feed into grid). Inverter power: 5kW AC output voltage: AC110V/120V or AC220V/230V/240V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 10kW solar off grid power plant is composed of solar panels, batteries, inverters and other accessories. This system can supply power to home loads independently, also it can be connected to grid or generator to take them as backup when battery is over discharged. Inverter power: 2pcs 5kw in parallel AC output voltage: AC110V/120V or AC220V/230V/240V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 15kw off grid solar system can be suitable for both residential use and commercial use. The output voltage can be single phase or three phase. Inverter power: 3pcs 5kW inverter in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 20kW off grid solar system is suitable for area without grid or grid is unstable. It can be compatible with generator to saving electricity bill and increase the power quality. Inverter power: 4pcs 5kw in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 30kW off grid solar power system can be used for remote area without grid connection. Wifi or GPRS monitor can be avaible for such system. Inverter power: 6pcs 5kw in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatiable with generator Monitor: WIFI or GPRS
The 40kw off grid solar sysem is normally used for area without grid connection or grid is unstable such as farm, hotel, small factory.
