Solar energy is a great renewable resource that is growing in popularity with the average consumer. As energy prices skyrocket and the average income stagnating, if not falling, consumers are looking for a way to reduce their costs of living in any area possible. The rise of renewable energy, and the desire to wean our society off of fossil fuels, makes using solar panels for the home a great alternative for power.

Solar power kits save energy for the homeowner because they allow the homeowner to generate their own electricity to power their home. In some cases, the homeowner can go completely off-grid and even sell additional electricity back to the power company. What a powerful concept to be able to take an expense and turn it into an asset.

What are solar panels?

A solar panel is a packaged interconnected assembly of solar cells that are cased in a housing unit to protect the cells from the weather and from physical damage. These panels generate electricity, which is then used to directly power devices in the home, or charge battery cells to store the power for nighttime use. A solar power kit typically includes solar panels, an inverter and interconnection wiring to connect the panel to the electrical system in the home. For those that want to live off the grid, batteries are included for continuous power during the day and night. The use of infrared solar cells also allows the homeowner to generate electricity at night, thus increasing the efficiency of these cells.

The technology of solar cells continues to advance with time. Currently, the efficiency rate of solar cells range from 5% to 19% depending upon the technology. The reason is that the solar cells (or photo-voltaic cells) only convert a limited range of sunlight frequencies into electricity. The renewable energy industry is experimenting with advanced technologies that will raise the efficiency of these solar cells by a whopping 50%.

A new technology for solar cells, also called thin film or third generation solar cells, is being researched. The plus side of this new generation technology is that it produces solar cells that can operate with a higher efficiency and less cost. These brands are both rigid and flexible thin film modules. The differences between the rigid thin film module and the flexible thin film module are due to differences in the materials that are used to make the modules and differences in the production of the modules.

Solar modules can last anywhere from 10 to 25 years while still operating at 80% of their original capacity. Every year the number of panels sold to consumers continues to grow. In 2007 over 4 million solar units were sold. There are a number of manufacturers that produce solar panels for consumer use, however the average consumer can create their own solar panels using materials from their local hardware store.

Solar panels for the home can provide renewable energy for the consumer. The initial costs can range greatly if the consumer chooses to build their own solar energy kit or have another company install a solar power kit. As the technology improves, the homeowner will have more options available to them to completely power their home with renewable solar power energy.

The most popular portable solar panel systems have to be the 12 volt system. Due to their sizes, they may not provide enough heat to warm your entire house, but they do offer more than enough energy to run your portable devices and recharge them. Like their much larger counterparts, they run better under direct and full exposure to the sun but obviously require more time to generate the same amount of electricity. They will also run on cloudy and rainy days, but not on indoor lighting. However, development of solar panels which work under indoor lighting is in progress and will be available to the market within an estimated 4 to 5 years.

Portable solar panels provide great convenience to people with lots of outdoor activities. They, however, need to be handled with enough care, just like any other technical devices.

1. Make sure your panel has built-in regulator.

The built-in regulator is able to control that the panel only generate the amount of energy that is required by the devices being recharged. This is a feature that all superior portable solar panels have, and it eliminates the risk of overcharging which may well destroy the device being recharged.

2. Avoid folding solar cells

In reality, portable panel systems are foldable and thus can be put into a big pocket or purse with ease. But the solar cells themselves are far from being foldable. It is exact the same case as a weight belt: it is flexible, but that’s only because the fabric they are attached to is flexible. Similarly, in case of solar panels, the fabric which holds them is foldable, thus allowing for the cells to fold with them.

Therefore, be wary of mishandling the solar panels. They may be advertised as being durable, hardy and waterproof, but under no circumstances should you fold the cells themselves, or pierce or poke them with anything sharp.

3. Do not use your panel to charge a regular battery

This may sound too obvious, but many people are still doing it. So, bear in mind that your panel only works for rechargeable batteries.

4. Buy customized connector for your panel

Equipment for connections should be bought separately as they aren’t provided. The recharging plugs in your devices should have customized connectors for them.

5. “Trickle charge” your car to make sure its battery is full

In case you plan to trickle charge your car, or snowmobile battery or boat, battery clips are essential. The portable solar panel is to be situated in such a place so that it gets the maximum amount of sunlight, after which it is to be plugged in to the cigarette lighter socket or the clips are to be attached to the battery. This really comes in handy when the temperature is really low, and you need to keep your car parked for indefinite periods of time.

Compared to grid electricity and the likes, portable solar panels are an expensive alternative, but they are very useful if you camp outside for long intervals of time, or like hiking or working inside your car. In addition, they are invaluable as backup systems during power failures.
