1 Heat insulation
The components on the roof can reduce the indoor temperature very well, especially in summer. The photovoltaic panels convert light energy into electrical energy. The photovoltaic panels are equivalent to the insulation layer. The actual measurement can reduce the indoor temperature by 3-5 degrees. In winter It can also effectively keep warm at the same time.
2 Save electricity bills
Perhaps many people will ignore the electricity bills of tens or hundreds each month, and the cumulative annual electricity bills will be thousands or even tens of thousands of yuan, especially for the owners of villas or self-built houses. Because the house is too big and uses more electrical appliances, electricity bills soar in winter and summer. In order to encourage residents to save energy, the state has also said that if there is excess electricity, the electricity bill will be even more frightening.
If photovoltaic power generation is installed in villas and large houses, and the grid-connected mode of spontaneous self-use of surplus electricity is adopted, most of the electricity consumption can be saved, and the tiered electricity price can also be avoided. A large amount of money can be left through photovoltaic power generation every year.
3 No pollution, no noise
Photovoltaic power is generated by inexhaustible solar energy, does not produce any pollution and noise, is truly energy-saving and environmentally friendly, and puts environmental protection into practical action.
Every kilowatt of photovoltaic power generated will save 1 kilowatt-hour of electricity = emission reduction of 0.997 kilograms of carbon dioxide = emission reduction of 0.272 kilograms of carbon. Calculated by installing 5KW photovoltaic equipment, 5982 kilograms of carbon dioxide can be saved a year.
4 Surplus power grid acquisition
The state supports "spontaneous self-use of surplus electricity to go online", and grid companies vigorously support distributed photovoltaics, optimize resource allocation and utilization, and save a lot of costs and time.
5 Trend, personality, beauty
The perfect combination of solar photovoltaic panels and the roof rejuvenates the original roof made of reinforced concrete, and at the same time makes the original homogenized roof more individual and trendy.
