Benefits of Green Solar Energy

Hi Guys,

I hope that you’ve all had a really great day.

We will be exploring the benefits of green solar energy in connection with renewable home energy.

Every 15 minutes the sun produces enough power to supply our current energy needs for an entire year. The United Kingdom due to its distance from the equator receives 60% of the solar energy received at the equator. This energy equates to between 900 to 1200 kWh per square metre per year.. This energy is equivalent to the energy production of 1000 power stations.

The energy coming from the sun fluxes and wanes depending on the solar activity. The less sun spot activity on our sun the less energy emitted.

To really understand and exploit the benefits of green solar energy, one needs to understand how solar energy is harnessed.

Green solar energy can be divided into two types i.e. thermal (heat) and light.

Thermal energy is considered passive solar energy. The use of passive solar energy in housing involves the placement of the building for optimum benefit, the building design and position of suitable building components to make full use of sunlight for day lighting, passive heating, and/or passive cooling. Apart from saving energy, the primary benefit of a passive solar home is the improved comfort of its occupants.

Thermal energy is harnessed through the design and materials used to construct a building.

The building gathers energy from the sun the old fashioned way; by allowing it to stream in through the windows…

By incorporating the right ratio of south facing wall to windows (if you live northern hemisphere) and using heat retaining materials, such as brick and stone and with a little intelligent design and planning, a passive solar home or building can get a full quarter of its heat from the sun alone. That same thermal energy can also be used to heat water for solar hot water systems.

In a passive solar house window placement and sizes are crucial as they can affect the heat gain or loss during various months of the year.

When designing and planning a passive solar home the ultimate goal is to have a home that is warm in the winter and cool in the summer. Passive solar home energy systems can easily be integrated with active solar systems.

A passive solar system functions best in an energy efficient home with a well designed mechanical system.

It unfortunate that in mass produced housing the principles of passive thermal energy are hardly ever used.

A passive solar system can only be a part of an energy efficient home and should not be considered as a stand alone solution to saving energy.

To reduce the need to use lights within the home during the day tubular skylights along with sky tubes and solar tunnels can be used.

The rays of the sun also produce light and radiation that can be captured by solar panels to create electricity.

For the majority of home owners the reason to use renewable home energy is to reduce their utility bills. Constructing a green solar energy system can come with a large initial investment, however they generally pay for themselves within a few years by providing either supplemental electricity or all of the electricity to your home or business.

Building your own solar panels, participating in government refunds and net metering, in which you sell unused electricity back to the power company, can reduce the cost of implementing a green solar energy system.

In addition, green solar energy systems require little to no maintenance after installation, as most have no moving parts.

You don’t have to construct the whole solar energy system in one go, you can easily construct solar panels in modular sections and incorporate them into your home energy system whenever you complete a new panel.

Green solar energy systems can be used by homes and businesses alike. If going solar cannot meet all of your energy needs, it can certainly reduce them. Utilizing Green solar energy can save you money, but it’s greatest benefit is to the environment and our future.

As always, I wish you everything I wish myself.

Until the next time.
