Solar energy is harnessed from the sun through photovoltaic cells or solar thermal systems, generating electricity or heat for various applications

The amount of energy you can expect from solar panels depends on several factors, including the location, panel efficiency, sunlight hours, and system size. For accurate information regarding solar panel performance and potential energy generation, it's recommended to contact Sri Balaji Energy directly or consult with a local solar provider.

Solar panels can still generate electricity to some extent during cloudy or rainy weather, but their efficiency is significantly reduced compared to sunny conditions. Clouds and rain diffuse sunlight, reducing the amount of sunlight reaching the solar panels. While modern solar panels can still produce electricity under diffuse light, their output is not as high as during clear, sunny days.

I don't have specific information about the research and development activities of "Sri Balaji Energy." The details of a company's research and development efforts, projects, or innovations can change over time, and new information may have become available since then.
