Yes that is the bottom line isn’t it ? Should be straight forward to answer if – the Ifs and but(s) appear and the issue becomes too confusing. Let me explain why. Installed Wp Vs What we actually get on field. Wp rating of the Solar Panel is…
Read MoreAs REhub started getting sold in different parts of India – one request we kept getting was the need for a display – it does not surprise me at all . I jog regularly and need the iPod Nano telling me the minutes I took to run each kilometer and…
Read MoreYesterday I received a call from a system integrator – who has been installing solar systems using PWM charge controllers and is looking at switching to MPPT charger. He has an experimental set up with a 200 AH batteries, 48V, 2500 Wp Solar panels : 250 Wp X 10 nos ,…
Read MoreThis is another very commonly asked question.Here are some guidelines to determine the size of install in India. Money as a constraint : If Rooftop schemes with reverse or net metering is available in your locality ( not unless you are in Gandhinagar for example http://mnre.gov.in/file-manager/UserFiles/presentations-pwc-workshop-06092012/GEDA.pdf) install as much as you have…
Read MoreAs we interact with a variety of different solar system installers, we have got this question repeatedly – does MPPT make sense in Indian conditions. The implied question is – MPPT controllers cost more than the PWM counterparts – is it worth the while to add this cost to the…
Read MoreREhub is based on an high efficiency MPPT charge controller with the ability to accept a wide input MPPT range ( e.g 17 – 65 V for a 12V battery system). System_integrators can use this to their advantage by a) Selecting PV panels that are mass produced and therefore of lower…
