How much photovoltaic power generation is enough for a 300 square meter villa?
The question of how much photovoltaic power generation will cost on the roof of a villa in Beijing mainly depends on the system capacity and the brand of power plant you choose.
With different system capacities, the cost of 3kw and 5kw is significantly different. For example, the 3kw Zhaoyangbao villa rooftop photovoltaic power generation system is 23,800, while the 5kw one is 37,800.
In addition, the price of vschoice of different brands will also be different. For example, the price of products chosen by first-tier major brands and those of second-tier and third-tier manufacturers is still very different.
Finally, it is recommended to choose the photovoltaic energy production system on the roof of a villa that best suits your real needs.
89 square meters of photovoltaic energy production is enough for a villa of 300 square meters. Household electricity consumption is calculated as 40 W/㎡, and 300 square meters consume 12 kW, i.e. 40 × 300 = 12,000 W. The photovoltaic power generation capacity is 135 W/square meter/hour, 12 000 ÷ 135 = 89 square meters, so 89 square meters of photovoltaic energy production is enough for a 300 square meter villa.
