Sun is the ultimate source of energy. This energy from sun is basically intercepted by the earth’s atmosphere in two forms i.e, Heat & Light. Over last few decades various advancement were made by the mankind to absorb these two forms of sun’s energy to satisfy the domestic and industrial energy requirement. The technologies which harvests the light (photon) energy and converts in to electricity is known as Solar Photovoltaic’s and the technology which harvest the heat form of energy and delivers low – high temperature heat energy is called as Solar Thermal Technologies .
The Solar thermal technologies are harnessing solar radiation and delivers heat energy. The technology can able to deliver heat from 60°C - 1000°C in the form of Hot water, steam and hot molten salts. This technology is basically classified in to two categories:
Solar photovoltaic technology harnesses the solar radiation and generates electricity. The array of solar cells arranged in a manner is called as solar photovoltaic module. The standard photovoltaic modules are available in the capacity of 250Wp/300Wp/330Wp which can be connected in series and parallel to get our desired electrical output. There are several technologies available in Solar PV
Solar Photovoltaic technology contributes a major role in generation of power in renewable energy sector.
Among the domestic and industrial sector approximately 50-60 % of energy consumption is in the form of heat energy. And whenever there is a requirement of such heat energy, solar thermal technologies are most suitable option. These technologies can able to deliver hot-water/steam round the clock with the integration of thermal storage systems completely from sun. Which in return it reduces the dependence and heavy investment of conventional heating sources.
Examples of applications of Solar Thermal Technologies
Domestic Sector: Solar Water Heaters,Solar Cookers, Solar Space Heating Systems, Solar Dryers, etc.,
Industrial Sector: Replacement of fossil fuel fired Boilers, Solar Community Cooking System, Process Heat Delivery, Solar Air-conditions, etc,
For installation of solar thermal technologies the following are the list of pre requisites.
“These guys are genuinely honest and very very professional in every aspect of the execution of the project they have taken over. Once they commit something, they will go out of the way to make that commitment good. A real pleasure dealing with Rigava and sincerely wish them success in life.All the very best”
“Rigava provides excellent execution in installation at a very reasonable prices. They assures good quality of products be installed. Installing solar system is no doubt expensive but for long run that’s one time investment to reduce the electricity consumption and the electricity charges. Also the after sale service is excellent, the team is committed to work and the clients.”
“Excellent execution in installation and commissioning. Recommended to all my friends who want to install solar panel to reduce their electricity bill.”
“After scrutinizing many solar vendors in regards to performance guarantee, I am happy to choose Rigava Solar as they made the project look so seamless in execution with their end to end service and the production is exactly what was promised. My electricity bills have reduced drastically and love the App provided to monitor the production. I recommend Rigava solar.”
“I was recommended Rigava Solar by my architect and after going through several proposal I choose Rigava as I found them genuine and passionate about Solar technology. The project was completed on time and with best quality and workmanship. I will soon ask you to increase my solar system capacity.”
“Zero electricity bill even after using 3 Air conditioner for 12 hours every day. This is amazing, Iam extremely happy with the system and one thing I would like to mention , sabse best investment of my life aur Rigava sabse best company hai for solar.”
“These people are extremely knowledgeable, they integrated my Generator with the solar Hybrid system. I have achieved my energy independence and will recommend others to do the same. Help environment become sustainable.”
“Extremely satisfied and well on time.”
“They helped me repair my solar system which was installed 3 years back. While many companies said no to me and said it will not work anymore, Rigava technicians went out of their way to find the fault and correct it. I wish them all the very best and recommend it to all my friends.”
