Home Solar Energy System

Energy Efficient, Home Solar Energy System Information becomes more and more important to us all in the face of a looming mortgage crisis and talk of a recession on both sides of the atlantic.

Energy saving has now developed duel benefits, attracting both the homeowners who especially want to help reduce greenhouse gases by reducing their energy needs, those that want and need to reduce their energy bills and of course as long as you are working towards your energy saving goals you can start to reap the rewards and create a more environmentally friendly home.

As fuel consumption becomes more expensive we find that we are working and striving to pay for our bills instead of having the energy simply there - working for us to make our lives more comfortable.

The result of these financial and environmental pressures are that it is no longer a case of only those homeowners who are 'into' saving the environment that opt for home solar energy system installations, it is now true that planning the right solar energy system for your home is the only sensible step for everyone with a home.

There are two completely different types of home solar energy systems on the market, different because of the way that they absorb the suns energy and different in the way that they use that energy.

The two different types of energy we create from the sun are seperated into Power and Heating.

Solar Energy Technologies

This is still a brand new and developing industry and home solar energy technologies are improving every year.

There is a battle on at the moment and it is a good one, we need it - companies are working around the clock to develop more cost effective means to capture and store more solar energy using smaller components.

You see, the biggest problems we have right now when we want to install the perfect whole house, home solar energy system are overall cost, equipement size and energy storage capacities.

The cost of solar panels will come down, future solar panels will not look like solar panels but will integrate into the normal structure of our homes and we will... eventually be able to buy batteries that will store enough energy for all our evening needs without us having to watch the watt meter.

And we would need a field full of solar panels to capture the maximum amount of energy possible within the relatively short solar window of optimum energy available, depending on where you live and the season.

Of course all calculations would have to take into consideration shorter daylight and cloudy skies in the winter, which is exactly when we need lots of evening energy to heat and light our homes.

Also if you are going to become a solar energy user 'pioneer' - you want to know that you at least have the best panels available at the time of your investment.


Home Solar Energy System - Solar Panels

The most expensive home solar energy system for domestic use is the installation of a solar panels and all the corresponding on-grid PV system equipment needed to generate and monitor energy for electricity.

These solar panels are known as Photo Voltaic solar panels and you would need a number of panels together, wired in series to form what is called an Array.

They are usually installed at a 40 degree tilt to be able to collect enough energy to feed your electrical needs - at least until you had to switch back to the grid in the evening.

The most important of my solar energy tips is to remind you that the solar panel itself is just there to capture the energy as it comes down from the sun - there are different standards and qualities of solar panels but what is really important is what you do with that energy once it is being collected.

A solar panel without use will gain energy during the day but then that energy will go nowhere and you will lose it all again at night.

Another tip is to carefully work out, based on your 'average' monthly electrical consumption - the amount of solar panels that will form your array - that you should install.

There are a number of other vital installations necessary to help keep you in control of the energy you are collecting at your home, like KWH meters, an inverter, DC and AC disconnects, as well as mounts and wires etc..


Home Solar Energy System - The Future

The biggest problem we have right now when we want to install the perfect whole house, home solar energy system is that we would need a hugh garage full of batteries to be able to store all the energy we might need when the sun goes down...

It is all very well developing better systems to capture more than the meagre 15% - 20% of the suns energy that we manage to hold onto, but if we don't have a system to effectively store that energy.

The future of successful home solar energy installation lies in total system cost and capacity.


Solar Energy Technologies

This is still a brand new and developing industry and home solar energy technologies are improving every year.

There is a battle on at the moment and it is a good one, we need it - companies are working around the clock to develop more cost effective means to both capture and store more solar energy using smaller components.

At present we would need a field full of solar panels to capture the maximum amount of energy possible within the relatively short solar window of optimum energy available, depending on where you live and the season.

Of course all calculations would have to take into consideration shorter daylight and cloudy skies in the winter, which is exactly when we need lots of evening energy to heat and light our homes.

Unfortunately right now it is only when you start to see a steep rise in the price from the basic mini panel and a rise in the amount of equipment that comes in a in a solar power package and the installation that is required - you know you are getting something that should actually help to lower your utility bills - at least until you have to switch back over to the grid for additional evening energy...


Home Solar Energy System - Payback

When you expect to be making savings right away, it can be disappointing to discover that the estimated time it takes to recover your initial investment can be so many years - that is until you can start to say that the solar energy you are collecting and using is not costing you anything.

Although the payback time for a solar water heating system is relatively short at only on average 8 years (again depending on your climate) the payback for a whole house electrical system is a lot longer - realistically, on average - about 30 years.

That can be difficult news to take when you are considering a solar investment and it is true that it is a long time, but remember that meanwhile you will be doing your part and have contributed to worthwhile reductions in greenhouse gases, purely because the day after installation you have lowered your demand for energy from the grid.

The initial investment will also seems like so much more of a worthwhile deal financially, if you manage to time your eco friendly conversion with an available domestic energy installation grant in your part of the world - why not pop down to your local building office, town hall or coucil offices for news, it only costs little energy to ask and a good healthy grant could well knock 10 years off your payback time...

So, are you ready to be something of a pioneer and make the decision to take the necessary steps to help make sure you are ready for the uncertainties of the future.

I do hope that this article sheds some light on the different systems available for domestic installations, and that you are now better able to decide on the best option for your home.

Are you going to take care of most of your own energy needs by installing your home solar energy systems this year!
