While studies have shown that rooftop photovoltaics (PV) adoption is more common among households that are wealthy, that doesn’t mean that poorer households can’t benefit from the technology. If these policies are implemented, more low income households will be able to adopt rooftop solar.
The PD recommends a $600 million equity fund for low income households that want to install solar. They also propose that the fund should not expire after four years.
In addition, the proposed tariff will create a funding stream that can help low-income households recoup their costs in ten years or less. By doing so, it will spur investment in disadvantaged areas.
Compared to majority-white census tracts, the study found that majority-black and majority-American Indian census tracts have higher rooftop potential. However, they have lower adoption rates.
The study also looked at how the distribution of single-family rooftop potential differed by racial diversity. By addressing both factors, it is possible to develop more comprehensive, holistic solutions.
One of the main advantages of solar energy is that it is renewable. Solar technology is not only becoming more popular, it is also becoming more efficient. Some solar batteries have even been developed, which can store heat, and control the ramp up and down of the power output.
It is not difficult to imagine how much power could be stored in such a device. Various battery systems are being developed to slow the ramp up and down to a rate of 10% per minute. The most impressive part is that the cost of storing this much energy is not prohibitive.
In fact, the price of concentrating solar power, which is a good source of clean energy, is expected to range between 10 and 13.5 cents/kWh in 2035.
While that is a lot less than the price of a gallon of gas, it is still two to three times more than the price of conventional sources of electricity.
This solar power is being used in several applications. It is not only being used in homes, but also in agriculture and salt production.
Cloud cover can reduce the output by 70% in a minute.
Other technological advancements in solar technology include the ability to store heat in molten salt. A 2.2 GWe solar PV farm in China claims to have a storage capacity of 203 MWh.
