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.

Solar panel kits are great for people who would like to start a green project at home on budget. But, not all kits will be suitable for your home needs, and careful planning is a must before you head off to the supply store.

If you have prior experience with installing solar devices, you may have good knowledge about which parts you need and how each of them works. You may just purchase your kit from an online store and resemble the parts with minimum need for technical suggestions or support.

However, if you are totally clueless about solar panels, you should do some thorough research and select a reputable supplier who provides quality service. You should only buy the DIY kit that are accompanied by installation manual, preferably with a good amount of illustrations. Check with the supplier whether he can also be accessed by telephone, as email communication may not work sufficiently for you. Ideally, the supplier can send over his staff in case you require in-person help with installation.

Turning to technical planning, it is crucial that you tell your supplier about your home’s current energy consumption status and your projected energy requirements, so that he can work out the exact size and configurations of the solar kit that will meet your expectation. Without this step, you may end up buying a kit that is either too big or too small, which will either waster you money or fail to perform required job.

Professional solar kit suppliers will also ask about the exact location of your house, how it is situated towards the sun, whether you have trees and other buildings around, and the average outdoor temperature year round. These factors will all impact on how efficiently your solar panel works, and determine what technical features your panel needs to have.

You also need to consider purchasing batteries for storing excessive electricity, so that you do not have to go back to the grid at nights or on raining days. There are a range of batteries to choose from. Different batteries have different life spans, different needs for maintenance, and therefore different prices. Getting expert help in your selection will allow you to get the best value for your money.

A word of caution about prices. Solar panels come in with a variety of combination of voltages and amperage, and hence price tags vary. Do your research first and you will understand why some are more expensive than the others and whether it is worth spending more. Again, seek the expert help from reputable manufacturers so that you only pay for what you want – no more, no less.

Going for DIY solar panel kits is no small project at all, however cost-effective it is compared to buying ready-made solar devices. As such, you should not just do enough research, but also ask all your questions and test the suppliers’ services before you spend your money. It costs you time, but you will be rewarded with a satisfactory purchase.

To answer the question about how solar panels work, you need to first understand there are two different types of solar panels – one produces heat and the other produces electricity, each having its own working mechanism.

The first type of solar panels takes the sun’ s thermal energy to heat water or oil through thermal collectors. Plastic piping and coils are usually used in these panels, and the sun heats the liquid that runs through the coils to pass on energy. These panels are generally used to heat swimming pools, spas, Jacuzzi, and hot tubs at home or work. When coupled with hot water flooring systems and baseboard units, they can also be used to heat the interiors of buildings. Once you have installed this type of solar panel at home, you can confidently get rid of any additional heating sources. Bear in mind, though, that a motorized pump is often required to help the flow of the liquid in the system.

The second type of solar panels (often called photovoltaic cell system) typically uses silicon as a semi-conductor material, and DC (direct current) electricity can be generated when silicon interacts with sunlight. Based on this working mechanism, these panels only work in the day time when sunlight is available. Dependent on the size of your solar system, the electricity produced can be used to power general house appliances or even the entire house.

In case you also would like to power your house with the photovoltaic cell system at nights or on unpleasant days, you will need to have batteries to store the excessive electricity. A cheap option is to use the lead-acid batteries that are commonly used in cars, but always remember to fill them with distilled water so that they will not lose their charge. You may also opt for more expensive batteries, such as the absorbent glass mat batteries. They are sealed and hence does not require distilled water to retain their charge. If you live in a cold area, gel batteries are good choices as they do not freeze in low temperature.

Both types of solar panels use a glass frame to hold the collection cells, and both require direct sunlight to function at their maximum capacity. Hence, the solar panels are usually placed to face south in order to gain the greatest exposure to the sun rays throughout the day. Although solar panels can be used anywhere to tap the sun’s energy, they obviously do not work effectively in places where cloudy weather dominates throughout the year!

The above is just a brief introduction on how solar panels work. If you really like the idea of getting solar energy for your home, you might also like to consider keeping a generator as a backup. Even if you live in a sunny area, there might be unexpected spells of rainy days, or your batteries may occasionally fail to store the electricity. You can run your generator on bio-fuel to ensure a complete green life.

Sara Magee asked:


Does a home or business in the United Kingdom receive adequate sunlight for the installation of solar panels or solar powered energy systems? The answer to that question is “absolutely”. While the United Kingdom receives approximately fifty-five percent of the solar energy compared to that which arrives at equator, it is still ample enough to operate an effective solar energy system on the south facing roofs of homes even in the northern parts of Scotland.

The key to purchasing and installing solar panels in the UK is to be sure they are mounted at the correct pitch, and never in the flat or horizontal position that will allow them to collect water. Any solar panels can quickly be destroyed when seals are compromised by standing water.

Another question frequently asked about solar panels in the UK is if they will be able to completely replace an existing electricity supplier. The simple answer to such a question, unfortunately, is “no”. At this time solar panels in the UK cannot harness and store enough electricity to completely furnish a home or business twenty-four hours a day. While it is possible to come very close to complete self-sufficiency through a combination of alternative energy sources, at this time a home or property owner will still require supplementary energy supplies from a utility company or energy provider.

Many home and property owners need guidance in deciding on what variety of solar panels they should install. Currently there are two types of solar panels in the UK: evacuated tubes and PV solar panels. They each serve a different purpose and can realistically be used simultaneously to meet a building’s energy demands. Evacuated tube solar panels are relied upon for hot water heating, while PV solar panels are those that gather and generate electricity.

How does a property owner determine the amount of energy they will require from their installation of solar panels in the UK? There are several recommendations for those considering a solar energy system for their home or business. The first factor involves itemizing exactly how many amperes will be required by the property during a set period of time. For example, a homeowner’s daily needs will be significantly longer than a business owner’s, and in both situations a twenty-four hour delivery of energy is not possible.

Because solar panels in the UK are powered by light collected from the sun, the evening hours do not allow for any energy production at all. Most solar energy systems do have batteries that store energy, but these do not currently exist with capacities large enough to function after the sun has set. In fact, most modern solar energy systems involve components that prevent the system from completely draining batteries of all energy as a way of enabling them to continue in operation the next day.

Ultimately, a home or business owner must simply consider their daily needs, configure that against the size and collection capacities of the system, and then add another fifteen to twenty percent to this overall figure to completely eliminate any possibility of total battery drainage.

Solar panels in the UK are an excellent investment in energy savings and greatly increase the value of a home or property. Current statistics indicate that most buyers are happy to pay an average £10,000 more for a home that functions with higher environmental and energy standards.
