Solar Pv Panels – How To Choose This Technology Wisely

Solar PV panels are a major component of solar power systems. The ‘PV’ refers to the photovoltaic effect, a process that converts sunlight into electric energy. The panels capture sunlight and transform into usable electricity.

Currently, there are three types of solar PV panels. These are:

#1 Monocrystalline Solar Panels

Although an old technology, monocrystalline solar panels are considered as one of the best. They are expensive to manufacture however they offer the best efficiency. This type of solar panel is made from pure silicon crystals that are sliced up thinly into circular wafers. Wires that look like silver lines run through these wafers. When sunlight hits each wafer and it is transformed into electricity, it is transmitted via these silver lines.

#2 Polycrystalline/Multicrystalline Solar Panels

This type of solar panel is made from slightly impure silicon than what is used to manufacture monocrystalline panels. Instead of forming from a single crystal, they are thrown into blocks. These crystals therefore get randomly arranged and are individually visible. When the polycrystalline slab is cast, it is cut into single square blocks. This is sliced into square wafers and further processed to be transformed into individual solar cells.

Polycrystalline cells are similar in performance and efficiency to monocrystalline cells.

#3 Thin Film Solar Panels

Thin film panels are manufactured using very different manufacturing methods compared to its mono and polycrystalline counterparts. Instead of cutting up large pieces of silicon into solar cells, a silicon-containing spray is coated onto a surface to transform it into a solar panel. The production procedures used to create thin film solar PV panels is more energy-efficient. Thin film solar panels have a shelf life of 20 years.

Thin film solar panels are much heavier than mono or polycrystalline panels. You need to have a very strong roof and capable installers installing them!

Switching your home’s energy requirements to solar power is both a wise and environmentally friendly decision. Not only are you reducing your carbon footprint, but you’re also taking advantage of savings on your next energy bill.

5 Compelling Reasons Why Everyone Should Use Solar Energy

Solar energy is taking the world by storm. As more and more people understand how solar technology works and how easily they can incorporate it into their homes, the more advantages they can reap of having such an energy system.

Apart from enjoying significant savings on your energy bills, the following five reasons will help you understand why EVERYONE should switch to solar energy:

#1 Beneficial to the Environment

Solar power is a clean and green source of fuel. It reduces the amount of carbon footprint. There is no component of solar power that adds to pollution. Apart from using some clean water, solar energy technology does not release greenhouse gases. This is why it’s considered an environmentally safe and friendly source of power.

#2 Protection from rising utility Costs

Traditional sources of energy such as coal, natural gas and electricity experience daily fluctuations in price. In fact, the cost of fossil fuel rises every year. Apart from being detrimental to the environment, their quantity is limited.

When you use solar energy to power your home, you are independent from electricity-use! You’re considered off the grid. You will enjoy very cheap energy rates throughout the day. The sun will continue to shine but its rates will never go up, thereby giving you energy security.

#3 Enables People to stay in Inhabitable Lands

There are many places on Earth where electricity cannot reach in high altitudes, mountainous peaks or arid landscapes. However, people still manage to live in such places by burning wood and coal. By installing a simple solar panel, these people can live more comfortably without the need to burn fossil fuels. In fact, more people would be willing to live in quieter and more desolate areas if solar energy is available to them.

Underutilized land can also be used to set up solar farms. These are large areas with panels that harvest massive amounts of solar energy. For instance, in the UK a 45 acre solar farm generates enough solar energy to power 2,500 homes.

#4Solar Power use equates to less loss of electricity

Traditional electricity is transported from large power plants via extensive networks before it reaches consumers. During this long distance transmission, there are enormous amounts of power loss.

With solar power, there is no energy loss whatsoever. Solar panels are installed on your roof. After receiving the sun’s energy, this is transferred via the panels to your home. This is an extremely efficient electricity system. This also gives you more control over your energy usage and bills.

#5 Better for the Economy

If more people choose solar energy, the demand for this technology will increase. More companies who are willing to install solar panels will be created and consequently more jobs, especially for skilled tradesmen. This promotes economic growth. For example, in 2015, there were 35,000 new jobs created in the solar power sector in the UK.

Solar Water Heaters – What They Are And How They Operate

Solar water heaters are a cost effective method of generating hot water for your home. They are suitable for any climate and the only fuel they rely on is sunshine!

Solar collectors and storage tanks are important components in a solar water heater. In a two-tank system, water is preheated with solar energy before entering a conventional heater. In a single tank system, the solar storage and back-up heater are both combined in a single tank. Solar collectors and storage tanks work together to produce heated water for residential use.

Solar-water-heater

There are two types of solar water heaters: passive and active. The latter relies on circulating controls and pumps, while the former one does not.

Passive Solar Water Heaters

This type of solar heater is more affordable than active types, however they’re not as efficient either. There are two type of passive solar water heaters:

Integral Collector Storage

This type is most useful in locations where temperatures rarely dip below zero. They’re also useful in households that require significant amounts of daytime and night time hot water.

Thermosyphon Systems

These are more expensive than integral collector storage systems. Although very reliable, the storage tank for the water is quite heavy. In this system, the water flows and rises as it warms. As a result, the collector is installed underneath the storage tank.

Active Solar Water Heaters

There are two types:

Direct Circulation Systems

In this type of system, water circulates through the home via pumps and collectors. This system is ideal for locations where temperatures do not fall below freezing.

Indirect Circulation Systems

A heat transfer fluid is circulated via pumps, collectors and heat exchanger. This will heat up the water before it flows through the home. This type of system is ideal for areas that receive freezing temperatures.

If you are searching for energy efficient ways to obtain hot water for your home, consider investing in solar water heaters. Not only will you enjoy the savings on your next energy bill but you will also be playing your part for the environment.
