1> Quick Detail:
A 12v solar panel is used in small solar applications to power on 12v electrical and electronic devices. These applications refer to motor homes and caravans or small solar installations like a shed or a garage. The size of your panel is dependent on the purpose you want the panel for. The size of the panel varies from 5 watts, 10 watts and 25 watts and is quite useful for charging your mobile phone, iPods, digital cameras and other such items. You also have large solar panels ranging from 30 watts, 40 watts and 80 watts. As a general indicator these panels are ideal for taking care of your appliances like refrigerators, television sets, satellite receivers, microwave ovens and other similar appliances.
12v solar panels are a very convenient and eco friendly way of generating electricity. Once you install these panels, you will not have to worry about any maintenance at all. In order to build a 12v solar system you will need batteries and a solar regulator (charge controller) to store the solar energy. By storing the solar energy in the batteries you can ensure that you have sufficient back up power irrespective of the weather conditions. You can use this back up power to take of your lighting, cooking, water heating and cleaning needs.
Fitting 12v solar panels helps in bringing down costs. Since these panels are ideally suited for motor homes and caravans, you can bring down your traveling costs drastically. This is because the 12 v solar panels absorb the energy from the sun and convert it into electricity to meet all your needs at no cost at all unlike traditional forms of generating electricity. There is only an initial cost involved for purchasing and installing the solar panels. Once the panels are installed there is no recurring expenditure involved like maintenance, etc. This naturally helps you save on fuel costs when you are traveling.
No wonder 12v solar panels are very popular amongst people who have motor homes, caravans and other such vehicles.
To make efficient use of the precious electricity made by either wind generators or solar modules and stored in batteries, it is most important to choose cables and fittings carefully. The right cables of the correct cross-section should be used to ensure safety, reliability and to minimise voltage drop and energy losses.
Larger wire sizes are required in lower voltage DC systems than in standard AC systems.
Cables consist of conducting wires with a protective, insulating covering which must be resistant to moisture, sunlight, heat, chemicals and abrasion. For better protection underground, outside or in harsh conditions conduit or armoured cable must be used. For outside applications, cables and other exposed external plastic fittings must be weatherproof and resistant to deterioration in sunlight.
All cables should be adequately supported using conduit, cable cleats, cable clips or cable ties etc.
Flexible multi-stranded wire should be used instead of single stranded wire to ensure good connections and reliability.
Standard 230Vac household ‘twin & earth’ type wiring uses PVC insulation which is somewhat resistant to sunlight (it should last about 5 years), and this is the cheapest choice for internal wiring such as DC and AC load circuits. Common single insulated wires are not sunlight resistant.
The production, use and disposal of PVC results in the creation and release of large amounts of persistent toxic & carcinogenic chemicals, including dioxin - a hormone disrupter, one of the most toxic substances known.
By using polyethylene or rubber insulated cables (described as halogen-free cables) in place of PVC this environmental contamination can be avoided.
