Choosing the best solar panels

solar panelsGas, oil and electricity power are non-renewal sources of energy. With the present day consumption of energy, these add to the causes of environmental pollution such as water pollution, noise pollution and air pollution. Moreover, energy produced by either of these methods is expensive as well, since, for example, to generate electricity from water a dam has to be built etc.

Solar energy on the other hand is a clean source of renewable energy. It is considered to be a more reliable, less polluting and economically viable energy generating system. Solar panels create electricity from the sun and this electricity gets stored in batteries unless it is used. There are basically three main components, the solar panels, a charge controller that basically turns the solar panels on and off when the batteries gets full which prevents the batteries from getting overcharged and the batteries. Electric energy is generated from solar panels with the help of photovoltaic cells.

As a result, there is a great demand for solar panels since they are able to operate weather satellites, household electrical devices, water turbines, industrial equipments and appliances etc. Frankly speaking, the size of each panel is proportional to the amount of energy that can be stored. With each solar panel being a store house of solar energy, the 12 volt solar panel completes the energy requirements for small boats, recreational vehicles, diverse electrical devices and all terrain vehicles.

There offer many advantages:

  • Long lasting and sustainable form of energy source
  • Renewable energy
  • No air or noise pollution
  • Negative deposits of carbon
  • Low maintenance
  • Electricity generation evenly distributed

But the most difficult question is how does one choose the best 12v solar panel? If you’re alright with calculations then fine or else one might require professional help, since the selection criterion is not easy with these easily usable devices.  Prior to deciding on the specific 12 volt brand or model, consider the following:

  • Daily energy utilization calculation: The calculation method is easy if the load consumption of electrical devices in use is mentioned.
  • The size of the panel: This needs to be checked since solar panels are available in all shapes and sizes. Don’t go with the size of the photovoltaic cells since some models might produce less electricity than is actually required.
  • Battery size and storage capability: Larger size solar cells such as gel batteries are unable to charge smaller size batteries. However, from a larger panel some could accept the electricity but one needs to be certain about it. The most important consideration is its storage capability. There is no need to purchase a costly solar device that misses out on battery storage capability. The storage capacity should be more if the solar energy is required for longer periods.

When deciding to purchase a solar panel, consider the above mentioned guidelines. This can also be done on one’s own, but consulting a professional in electrical devices is highly advised.

Using Renewable Energy Sources as Backup Power

Backup PowerAlmost all equipment present inside a modern house runs on electricity. Stoves, kettles, juicers, televisions, computers, water filters, refrigerators, dishwashers, water heaters, space heaters, air conditioners etc all are electric powered and things get really tough when there is no electricity. Power lines are down after earthquakes, volcanic eruptions, floods and thunderstorms. In extreme cases power outage can last for several days or even weeks. Everyone needs to have power backup for surviving in such conditions.

Backup Power Sources

Renewable energy sources, especially solar power systems are now being used as the main power source. The only downside of solar power systems is their high onetime cost. Most people don’t have enough money to purchase large solar systems that can power a whole house. Small solar power systems are available at highly affordable costs. These units can provide power to lights, fans, refrigerators, stoves, water heaters etc. but not altogether. You can manage to run almost all home appliances with smaller units. If you need to turn on the water heater you can turn off the stove or fridge for a while to avoid excessive load.

Solar Power Systems

Small sized solar power units are the perfect choice for backup power. In normal days when you are getting grid power, the solar system can be used to heat water so that the unit remains in running condition, and also saves you some money. Small solar panel units are available at highly affordable costs. You can even build a solar panel system yourself to save some extra bucks. Search online and you can come up with several websites that deliver solar panel systems or equipment at your doorstep. Solar systems include photovoltaic panels, controllers, batteries and output sockets. The batteries store energy and they can provide backup power even if there is no sunlight on a particular day.

Wind Power Generators

Other renewable energy backup power solutions include wind generators. These generators allow you to convert average speed wind into energy that can easily power numerous electronic appliances. Wind generators are easy to assemble. A man that easily handles small domestic hardware tasks can also combine different components of a wind generator. Small wind power systems are available at quite affordable prices. Petrol or diesel generators are usually not the perfect backup choice as getting fuel on a disastrous day is quite difficult. Gas stations are closed during floods or storms, and people don’t even get a chance to step onto the roads, so these generators become useless in extreme cases.
Conclusion
Every household should be prepared for emergency situations and backup power should be given top priority. One can live without food for a couple of weeks, but surviving without clean water is very difficult. Water can be cleaned by boiling it on a stove or by a using water filter, and both these things need electricity to work. Kids start to cry in the dark, but if you have backup power you can easily light your house. As mentioned above, renewable backup power sources turn out to be the best choice during calamities. So, every house needs to have a alternative energy source.
