(1) BIPV can enhance the aesthetics of the building, the use of "roof tiles" to replace the original roof of the building, the effect is the same as the original roof tiles, but also play an economic role in power generation. Once the photovoltaic power generation system is completed, the energy consumption of the building will be greatly reduced.
(2) photovoltaic roof on the environmental pollution is small, and can reduce a large number of CO2, according to the relevant reports, photovoltaic battery cumulative amount of 600MW, equivalent to about 590,000 tonnes of carbon dioxide emission reduction per year. For every unit of electricity produced, about 350 grams of coal is needed. Coal is the main source of greenhouse gases, and solar photovoltaic power generation can greatly reduce the burning of coal.
(3) Under sunshine conditions (under 1000W/m2), installing a solar power system, 1 square metre of roof can obtain 130-180 watts of electricity, so that the building can make use of the electricity generated by the battery module for daily life, and when there is excess electricity, it can also be sold to the government to obtain a profit.A solar pv racking system can last up to 20-25 years and requires little maintenance during its lifetime, so the investment in a BIPV is basically just the initial investment cost. The payback period for a solar power system is about 12 years.For a home user, investing in BIPV will be a relatively substantial figure.
