Proper maintenance ensures that solar system life is preserved for as long as possible and the original conditions of the system are sustained while compensating for normal wear and tear. Solar systems require little maintenance as compared to other electric systems such as diesel generators; however, they are not maintenance-free. Read more
To get a Solar PV system installed, it is important to understand the various components and factors that are in play.Given the size of the investment, it is absolutely crucial to know everything about the product and its specifics, so better decisions can be made when it comes to making Read more
Over the past couple of years, battery technology has improved significantly with many new lithium battery types emerging as manufacturers explore different ways to add or couple batteries to new or existing solar systems. The original Tesla Powerwall was the first ‘high voltage’ DC battery system. Ever since its introduction, Read more
Overcurrent Protection Device (OCPD’s) is critical to personal safety and protection from a number of hazardous conditions that can result from materials igniting due to improper overload protection or short-circuit protection. Overcurrent protection devices are meant to protect against the potentially dangerous effects of overcurrents, such as an overload current Read more
There are are a few basic factors to consider when designing any kind of system. Energy requirements2. Peak Sun Hours3. Site Location Evaluation4. Battery bank5. No. of Solar Panels Off-grid systems are designed to work alone and are sized so that they work during the worst conditions of the year, Read more
There are a series of important questions that come to mind when talking about sizing a PV system. 1.What is your monthly electrical usage? Your utility bills will show you how many kilowatt-hours of electricity you use on a monthly basis. You can calculate the watt-hours of each appliance you Read more
Manufacturers quote the efficiency of a PV System at STC conditions, i.e. at 1000 W/m2, however, due to parasitic resistances the efficiency is not constant as the intensity of solar irradiance changes. This is referred to as Irradiance loss Irradiation losses seem to be rising from spaces in between two Read more
Module Mismatching When PV modules are connected in series, there is something known as “the Christmas light effect”. If one module has less current, then it eventually limits the amount of current to flow through the whole series-connected PV source circuit (string). Before there were bypass diodes in PV modules Read more
Blocking Diodes A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from the battery to solar panel thereby preventing the battery from discharging. Current streams from high to low voltage, so on a bright day, the voltage of Read more
