What are the best types of batteries for off-grid small solar power systems


There are many types for batteries available for off grid solar power systems as follows:

1. Lead acid battery with or without maintenance

2. Lithium ion battery/ LiFePo4 battery

If you have enough space available & cost is concern, you can go with the lead acid battery. If you need light weight option which can give you more energy  & uses less space, you can go for lithium battery. 

The another advantage of lithium battery is that , it can be discharged for 100% unlike lead acid battery which can be used for upto 70% of its rated capacity.

What are the Reasons for Using Solar Hot Water Heaters

Image
  Many people use the electrical heaters to heat the water. These heaters uses high grade electricity to convert into low grade heat. So its conversion efficiency is very less. Some people use the gas geysers to heat the water which also has its own pros & cons. The solar water heater on other hand usage the freely available heat from the sun. The solar water heater The solar water heater captures the heat from sun and transfers it into the water to make it hot. As it don’t have any mechanical moving parts, it don’t   need any major maintenance. So solar water heater is the most efficient way to heat the water.

What is the Most Efficient Solar System for Home Use

Image
There are many types of solar water systems for home use such as solar power generating system, solar water heating system, small off grid solar systems. If your aim is to have solar system then you can go for the solar grid connected system. This is more efficient than the off grid (with battery) system, as it requires little maintenance. It has designed life of about 25 years. So installing grid connected system for your home can be a wise decision. If you are using larger part of electricity for water hearting purpose, you can go for solar water heating system .

What is the Types of Solar Water Heater System

Image
  Solar Water Heating system are of Two types  1. Flat Plate Type Solar Collector 2. Evacuated Glass tube type Solar collectors Below are working principle for solar water heater system: • Thermosyphon system : Natural circulation by gravity.  • Force Flow system : forced circulation by pump.   a)      Thermosyphon – Water in solar tank circulates naturally   through the collectors due to the difference in specific gravity of hot and cold water.  In this system, the temperature cannot be controlled, and as hot water is used from the tank   b)     Forced Flow – The flow in this system is controlled through a control panel with digital temperature controller and pump.  The cold water is circulated through the solar collectors and allowed to stay there until the set temperature is reached. Once set temperature is reached  then the pump comes on and pushes the heated water into the storage tank.  ...
