A Solar System generally  comprises of the following elements: Solar Panel, a Charge Controller, a Power Inverter, a Monitor and Electrical Distribution System. As seen with each other technologies each component has different manufacturers , quality, features and price. Solar Panel: A Solar Panel consists of silicon crystals which converts the rays on the sun […]

Ripple content on DC side – Rooftop solar system

Posted · Add Comment

Ripple current is the small unwanted residual direct current (dc) power supply which has been derived from an alternating current (ac) source. This ripple is due to incomplete suppression of the alternating waveform within the power supply. PV modules produce Pure DC Voltage and Current without any ripple, however inverter operation influence the voltage on the DC side, and  have a backlash […]

Battery and Charge Controller – Roof Top System

Generally, the batteries are provided are of 2V cells connected in series to reach the system voltage. Battery shall be suitable for charging from SPV system as well as from the grid in case of grid interactive system and with SPV system alone in case of stand alone system. Normally in a solar PV system with battery, battery is […]

I-V curve importance in Roof Top system

Posted · Add Comment

By looking at the I-V curve it shall be possible to know about the optimum power to be delivered by the SPV panel/array/source.The peak hour behavior of current and voltage can also be estimated from the curve. A module which is rated at 17 volts will produce less than its rated power when used in a battery system. This […]
