Solar fluid maintenance in solar water heating system

Solar system for water heating can work without any maintence work.Only thing that must be taking care of is solar fluid.In  system for water heating we use Glycol/water mixtures.During cold weather it esential to check freezing point of your solar fluid.
It should be at least -20 celzius.In some system you can drain fluid during winter when solar system is not in use.This winter in Europe temperatures can be even -30 C, Glycol freezing point can measured using  Glycol Antifreeze Pocket Tester.Be aware some testers that are used for cars antifreeze wouldnt work with Glycol fluid.

Solar lights

Solar garden lights are an amazing concept. The simplicity of solar garden lights stuns everybody, as there is no need of wiring or assembly. One can very easily get them started by taking out of the box, pushing the button on and setting it in the sun.
Solar garden lights use the sunlight to light up and glorify the garden. They resemble the rock somewhat which perfectly gets blended into the garden. Everybody praise these lights and is keen to know about its working. The garden lights can be changed on different occasions which gives is it’s another plus point.

Solar lights are mainly used in gardens and around houses.Main advantages are low cost for electrical energy consumption, you don t have to worry about cable in your garden.Also good thing is automation, solar lights turn on their  bulbs automaticly every evening as soon there is no daylight.

Passive Indoor Heating

It is amazing to get warmth of sunlight on a chilling winter day. Making use of solar energy for heating ourselves and our indoors is what we call passive indoor heating. Passive indoor heating not only cuts down our huge expenditure which is made on making arrangements and purchasing appliances for heating our households, but it also helps to contribute in reducing pollution levels.
One can take advantage of sunshine by removing the trees etc which block sunlight to come in. and at the time of constructing a new house, the structure can be made which allows maximum sunlight to enter from windows during winter so as to get benefitted by passive indoor heating.

Passive solar energy

The solar energy is broadly classified into two kinds: Active and Passive. Passive solar energy is the heat of sun which we get sitting at our homes. The concept of passive solar is amazing as it helps you to utilize the power of sun for heating yourself and your households and thereby cutting down your high electricity bills.

The statistics tell that people spend thousands dollars  every season for heating their homes. Passive solar is something which can help you out by reducing or almost removing the expenditure of heating. Passive solar uses the elements like windows, roofs and floors to get solar energy for your homes. The sun keeps shining all the time so we can make use of its abundant sunshine for heating our homes even on the coldest days.Passive solar not only aids us in saving money but it also contribute towards reducing pollution levels by making you use less energy. It does not have any mechanical parts or involve any moving, and that’s why it is called ‘Passive’ solar energy. There can be many uses of the passive solar heating varying from heating water for your shower or heating an entire household.

Photovoltaic solar panels

Solar Panel Photovoltaic is basically a method by which electricity is generated by converting solar radiation into direct current by making use of the semiconductors that demonstrate Photovoltaic effect. In this process of power generation by Photovoltaic solar panels composed of many solar cells containing photovoltaic material are employed.
The manufacturing for solar cells and photovoltaic arrays has gone up due to the increasing demand of renewable energy sources. Photovoltaic are best known for converting electric power into flow of electrons by using solar panels. This photovoltaic effect refers to exhilarating electrons into a higher state of energy, allowing them to act as carriers of charge for an electric current
