We have got a solar power plant with battery bach up by Primus in Narwal, I must say, excellent plant performance.
We have got solar street lights installed on our farm house by Primus Energy. We have light in our farmhouse from sunset to sunrise. It switches on automatically in the evening and swtiches off automatically in the morning. Saves electricity and need no manual labour. Very helpful.
I think Primus Energy has solved all our problems. Being a farmer in Rajasthan, it is very difficult to sustain yourself and your family due to lack of water and electricity. Primus Energy has installed a solar water pump for us, since then we have both water and electricity. It starts automatically in the morning and switches off automatically at night.
We have got solar water heater installed by Primus, very satisfied with the system and I think they are best in the field regarding solar water heater.
