PV Direct Solar System

Photovoltaic (PV) solar panels contain solar photo cells that convert sun’s energy to Direct Current (DC) electricity. Decades ago this technology for high energy production was something we could only see on TV and magazine photos used by satellites and space stations. Only PV cell that came in common use was the inch long solar cell in the humble pocket calculator. Well now everyone can have a high energy production photo voltaic solar system on their roof!

A PV-Direct system is a very simple solution which has no batteries to store excess energy and is not connected to the main power grid. The solar panels produce DC current feeding it to a simple solar inverter or Charge Controller, just like the electricity coming out of the main grid power socket. With this system you use what the sun currently gives and during cloudy days and at night there is no power available. Although these are simple to build and cheap to maintain, the modern household, agricultural or industrial enterprise demand a more reliable solution.

How to Size Your Off-Grid Solar Batteries

If you are designing a solar electricity system and don't have access to the grid, you are going to have to deal with batteries. When you start looking at solar batteries you are going to encounter a little math. Fortunately, SolarTown is here to guide you through the calculations! The general goal when designing an off-grid battery bank is to get a system that is big enough to supply all your needs for a few cloudy days, but is also small enough to be charged by your panels. Step 1: Calculating Your Amp-hour Needs 1. Inverter size To determine the inverter size we must find the peak load or maximum wattage of your home. This is found by adding up the wattage of the appliances and devices that could be run at the same time. Include everything from microwaves and lights to computers and clocks. The sum will tell you which inverter size you need. Example: A room has two 60 watt light bulb and a 300 watt desktop computer. The inverter size is 60 x 2 + 300 = 420 watts 2....

SOLAR BAG

THIS IS AN SOLAR BACKPACK TO CHARGE ALL YOUR DEVICES WITH A REMOVABLE POWER BANK Step 1: COLLECT ALL Solar panel bag powerbank connectors gluegun soldering iron Step 2: Attach the Connctor to the Panel Solder a diode and the connector through wires to the solar panel Step 3: MAKE THE POWER BANK READY ATTACH THE FEMALE CONNECTOR TO THE POWER BANK Step 4: Paste the Solar Panel on the Bag Using glue gun attach the solar panel to the bag Step 5: DETAILS this is a 2600mah powerbank or more as u wish charging time is 10 hours for power bank then it can charge a iphone once solar panel is 6v .1watt Step 6: ALL SET READY TO GO FIRST CHARGE YOUR POWERBANK IN THE SUN WHILE OUT Step 7: NOW YOU CAN CHARGE YOUR PHONE charge ur phone or any other device with the removable power bank
