PV cells are use semiconductors to turn sun radiation into electricity and are usually made of a special photovoltaic substance comprising cadmium telluride, mono and poly crystalline silicon, copper indium sulphide and amorphous silicon.
At this time there are many photo voltaic material in the solar market:
- Mono crystalline Silicon(Si)
- Poly crystalline Silicon (Si)
- Amorphous Silicon (a:Si)
- Cadmium Teluride (CdTe)
- Copper indium Gallium Selenide/Sulphide (CIGS)
When you connect multiple PV cells they will form a solar panel.
The PV panels (mono and poly) are rated according to the peak power they produce in watts DC.Read more: Mono vs Poly solar panels and cells

MPPT (Maximum Power Point Tracking) Solar Charge Controller is an advanced type of solar controller. They are designed to help solar panels charge one (or more) batteries at maximum efficiency.
So how exactly does MPPT work? (Maximum energy point monitoring)
Here is where maximum power point tracking comes in. Assume your battery have low voltage (12 volts), a MPPT solar controller takes that 18 volts at 7.2 ampers from your 120W PV panel and converts it down, so that what the battery gets is now 10 amps at 12 volts. Now you still have almost 120 watts. Thus increasing the efficiency of your PV system.
An MPPT regulator is a high frequency DC to DC converter, take the DC input from the solar panel change it to high frequency AC, and convert it back down to DC voltage and current that exactly match to the batteries needs.
What Benefit of MPPT?
- the efficiency of all MPPT charge controlis are between 93 in order to 96 percent
- the MPPT charge controller is advantageous in winters and cloudy days
- an MPPT sun regulator could be a beautiful an alloy with a grid-tied sun module
- Preventing reverse-current flow
- convert extra voltage into amperage
- MPPT charge controller will also largely eliminate an amount of power loss from a solar power system
- inferior gauge wiring could be used Read more: MPPT Regulators

A photo voltaic charge controller adjusts the flow from the charge in the solar panels towards the batteries. It provides the best charge volumes in the proper time to ensure that the photo voltaic batteries aren't overcharged. The present passing with the photo voltaic charge controller charges the batteries utilized in household products. This current may also be passed towards the invertors for transforming household power (Electricity) to alternate current (AC).Read more: About solar charge controllers

The Solar industry now offers a wide choice of products for your home that use the sun's energy, now include PIR sensors so the light comes on as we walk to our door.
This simple device can be very useful in your solar system.
Can be used in for warehouse light, corridor light, basement light.
Has two options during setup, one for light duration and one for the light sensor, through two variable resistors.
Comes with two mounting brackets, one fixed and one movable as shown in the pictures
Passive infrared (PIR) sensors are some of the most widely used kind of sensors utilized in houses and companies, mainly for that efficient way they are able to differentiate between your actions of humans along with other types of actions. Persons who're trading during these items must always aim to learn how to maximize their benefits.
