We get questions from clients about oversizing of inverters and why we are connecting more panels to an inverter - like connecting 33 kWp of panels to a 27.6 kVA inverter. Isn't this inefficient or a wastage of solar panels? Let's say that we are using 380Wp panels. The panel is rated 380Wp under STC [...]
A lot of questions still arise in the solar generation system, Whether the system will perform? Will my solar panels work even for a year or so? Will my inverters work? And so on….. In this article we answer all of these questions about solar generation in Bangalore as we have the data of [...]
Till recently the policy in Karnataka for some of the consumers had been Gross metering(GM) and some had Net Metering(NM). A recent circular from BESCOM has given option for some of the consumer segments- residential, hospitals and institutional the option for opting between gross and net metering. So what are the two types of metering? And [...]
With Ranga and myself already on site, waiting for team to come for next interesting project. In-fact it will one of the most challenging projects in our list. We are prepared to stay in an half built house, between the dense forest surrounded by the gigantic Banasura hill and other small hills covered by greens everywhere. [...]
Time for us to leave to Western Ghats,Waynad. Two of us started to Mananthavaady to check the problem with few installations done by group of volunteers earlier amidst the mountains for the adivasi people. Lighting their houses in such a beautiful place. We are excited. Excitement never comes alone. We had some tension same time [...]
With the world advancing towards automation and innumerable devices making our lives progressively comfortable, the threats posed to our mother nature are being not accounted for. One of the eco friendly tasks that an individual can easily go for is to opt for solar power. There are many places where we receive plenty of sunlight, [...]
Not the usual day it was. Very lovely weather. Mesmerizing for people working in Sun. We started to our site having hot tasty breakfast of our choice. We started with an enthusiasm that we will finish installation of 1000 panels crossing 300 kW on the project we are working. Started at our usual time 8:45 [...]
It’s customary for a PV system integrator to do a Site survey and collect information about local conditions and issues  before any proposal is made. The information collected is then combined with the load patterns and the customer preferences to make a final proposal. There are lot of aspects in doing a site survey for [...]
There are three type of On grid or grid-tie inverters (for details on what is a grid-tie inverter, you can refer to an earlier post  http://goo.gl/0jtWMl). They are 1. Micro inverter 2. String inverter 3. Central inverter. A Micro inverter is connected a single solar panel to  convert its generated DC current to AC current. This [...]
Harsha sent me an urgent email this morning. He said, "It might be true that sun can give 5 units/m2/day. But because the efficiency of solar panels is only 15% and there are losses in the system, we only produce 0.30 to 0.6 units/m2/day. Â For example a battery based system will give you 3 units [...]
