How To Get Started With A Residential Solar Power System?


It is said that the energy produced by sun for twenty days is sufficient to meet the entire energy requirement of the world for one year; this is the power of solar energy.

If you are thinking of installing the right home solar power system which meets your requirement, you must read this blog post, so that you can get an idea about the system.

You are not alone there are many people who are looking for solar power which is not only cheap but is also environmental friendly. You need to look at the pointers given below which will give you more information about the solar power energy and your home.

Firstly you must decide if it is the right time to have home solar power system? Solar power is fast becoming an affordable option which people are considering to run their homes. There has been marked improvement in the techniques of using solar power; the industry has become more matured in the last one decade.

The initial cost which was very high initially has considerably dropped by almost 40 % in the last three years. Probably no other time is more suitable than this time to consider having Photovoltaic (PV) solar power in your home.

Since the initial cost has come down, you will be able to recover the cost within 8 to 12 years. Let us see whether solar power is the right choice for or your home is quite suitable for the solar power.

Before anything else, you will have to implement some changes to cut energy usage and make yourself a suitable candidate for a clean renewable solar panel system.

Have you switched to CFL bulbs? Have you switched to energy star appliances? Are you the one who are using smart power strips to switch off the power when not in use? These are the things you should look into at your home before implementing a residential solar energy system.

Do you have a proper insulation in the doors and windows? If you have not done it and you are not sure how to do it, seek the help of a professional. They will do energy audit of your home and suggest the ways to save the energy. This will help you to save energy thus reducing your monthly electricity bills.

Now have a look at the roof of the house, your roof must be ideal for a home solar power system. You must ensure that your roof is facing south without any obstruction. Such situation is ideal to setup the PV panels to catch the energy from the sun.

But in case your roof is on east-west but is fully exposed to sun or you may use the option of ground mounting system, it has to be free from obstruction. You have to ensure your solar power system is free from shade all the time; shade will reduce the effectiveness of the system.

When you are ready, calculate the cost of installing the solar panels and other equipment, the cost will depend upon the type of solar panels you choose. You must see if there is any subsidy or rebates available, as most of the governments encourage installing solar power and give incentives.

You can also find a company who will fix the panels free of cost. You have many options, do a proper research and enjoy the cheap solar power.

Are you looking for ways to build a solar panel with a budget of less than $150? If you are, check out the Power4Home guide by John Russel. Read up on the Power4Home review on this blog for more information.

Easy Steps To Lower Your Home Heating & Cooling Energy Consumption




Power consumption is for sure a substantial part of our monthly expenses; though we usually accept it as an item we can do little about. If analyzed, it is found that the major chunk of our domestic power consumption comprises heating and cooling gadgets.

There are some tips that can very effectively help bring down power consumption and result in a substantial saving by way of reduction in power bills. Being a bit conscious of the options available for the types of heater with its running cost in mind goes a long way in making huge savings.

Do not just go and buy the first available electric heater; make some inquiries whether a gas heater could be an option and if so, which way you end up paying lower running cost. It may also depend on the availability of sources of power in your area and no one stops you from going in for the type of gadget that would be economical to use at your location. The same considerations hold true if you are going in for changing an old heater.

It pays to learn to regulate the thermostat; though not too technical, most of us take it to be something not to be fiddled with. Only few are aware that thermostats with timer can automatically regulate power to be just required for day and night time; and the results would perhaps pleasantly surprise you with the economy.

Most of us are quite comfortable with temperature settings of 70 and 50 degrees respectively during day and night time. It serves well not to change these settings too frequently as each change causes extra power consumption.

During spring and fall when you feel comfortable in your light woolens, it is advisable to switch off heating system. Inefficient or worn out insulation on the doors and windows in your house too is one of the major reasons for unnecessary power consumption; getting storm doors and windows installed does help save power particularly during cold season.

Warmth received from the sun needs to be put to best advantage; letting extra sunlight enter the living area by folding the curtains and trimming tree branches that obstruct sun also keeps the load on your heating system lower. Areas like attics and basement that do not have heating panels need to be better insulated.

Getting the heating system serviced by professionals before the onset of winter keeps it running with optimum efficiency when the load on it is at its peak. You may even use your common sense to see that the air filters are kept clean and the approach to the heating equipment unobstructed; these are commonly missed points of power wastage.

Inquiries should be made with your electric company to know if units consumed during peak and non-peak hours are charged at different rates; if so manage your consumption judiciously. A small example of this is that washing machine can be timed to operate during ‘cheaper’ hours.

Likewise, inquiries with the electric company can make you wiser about other steps for energy saving. It just needs you to be conscious of the economy in domestic power consumption you can bring about without subjecting yourself and your family to any discomfort.

I believe you can agree that the suggestions above are not too difficult to do. It may seem like a chore, but believe me, the amount of money you’ll save on lower electricity bill is well worth it. After you have done every possible thing to make your home more energy efficient, you can now implement a home solar power system to supplement your energy needs to bring your monthly electricity bill even lower.

Comparing Direct Grid-Tie With Battery Based Home Solar System




Solar power installation at home can either be directly tied to the power grid or it can be independent of the power grid. Both systems have their own merits and demerits.

Solar installation connected to the power grid is easy to install and the system ensures uninterrupted supply of power to the home. If the power supply from the power grid is unreliable, the home owner can use back up batteries or portable generators.

A solar installation not tied up with the power grid has to use electrical appliances of 24 volts DC. Though this system is ideal for places where mains electrical transmission lines are not there, it cannot serve all household purposes. However, a power inverter can convert the DC power stored in the battery to AC power.

Tying Up Solar Installation With The Power Grid

This is the easiest solar system to install since the system needs only the solar panels, an inverter and a switch. The inverter is connected to the power grid’s supply line through the switch.

When the solar system produces more energy than the needs of the home, the excess energy is transmitted to the power grid. When electricity passes on to the power grid’s power pool, the electric meter spins in the reverse order. The reverse spinning of the electric meter quantifies the power supplied to the power grid and the home owner is paid for the power according to the reading on the electric meter.

The meter has to be the one installed by the power grid because all meters cannot record the amount of power supplied to the power grid by spinning backwards. Having your solar installation tied up with the power grid offers other advantages also. Since there is an inverter, you can use home electrical appliances which work on AC.

All your home electricity needs will be met by the energy produced by your solar installation. Since batteries are not needed, your installation cost will be less. The system doesn’t need repairs often.

An advanced technology uses micro inverters where each solar panel is connected to separate inverters. The advantage of this technology is that even if one solar panel fails to produce energy, the other panels will continue to produce power and your house will have an uninterrupted supply of power.

Off Grid Solar Energy Installation

If the solar installation is not tied up with the power grid, the system has to have batteries to store the excess energy produced. Adding batteries to the system complicates the system and there will be recurring maintenance costs.

The inverter has to be a special one, capable of converting DC to AC and automatically switching on to DC if AC fails. The batteries will cost an addition amount of 4 to 5 thousand dollars. You also have to have separate wiring for appliances which work on DC.

A battery based solar installation needs to have other back up power production devices like a gas or diesel generator because the solar power produced during bad weather conditions will not be sufficient to meet the energy needs of the house.

The only plus point for a battery based solar installation is that the inverter doesn’t have to be connected to the supply lines of power grid and there is no need for the switch to shut off power supply to the power grid.
