What is a renewable energy system?
A renewable energy system uses sunlight, wind and/or water power to produce
electricity to power your home boat, camper, holiday home, street lights or sign lights.
A basic system is comprised of four basic components: solar modules and/or wind generator, charge controller, batteries
and an inverter. Energy is collected at the home site by the solar panels, wind
generators, or hydro-electric generators and then stored in batteries for later
use.
What size electric system do I need to run my home?
The
recommended size of your system will depend on your power consumption. If you
want to completely replace your current electrical purchases from the utility
with a renewable electric system, the first step is calculating your power
requirements. We assist you through this process and if you
design an energy efficient home, you could cut your electricity usage
dramatically, reducing the size of system you need. In the real world, the
majority of home systems range from 1 kW to 4 kW. Where you live, if you are on
the grid or off, and how you live, will dictate the size of your system and its
ultimate cost.
How much does it cost?
The cost of a PV system is not directly related to the size of one's home. It actually depends on how much
energy (kWh) you use per day and your location as well as how much sunlight wind or water power you get.
System size and cost are directly related to the number of appliances
used and the length of time they are used. Simply put: the power collected must
at least equal the power consumed. By analysis of the expected electrical
loads, we can size the system to provide
what the homeowner needs and can afford.
Beyond the initial cost of the system components, there are no
monthly electric bills. The system will continue
to pay for itself by providing reliable electrical service for many
years. The typical
system can cost from, 5,000Euro to over 40,000Euro depending on your kilowatt hour useage.
How difficult is the system to install and manage?
The new,
state-of-the-art alternative energy systems are remarkably simple and reliable.
Those homeowners with average mechanical abilities can easily install and
maintain their own system. We can provide installation, maintenance and repair services.
How long will my renewable energy system last?
Most solar modules have a 20 to 25 year output warranty, and will last even longer
no one can say for sure as the PV technology is not around long enough. Other system components
have varied lifetimes. Batteries can last up to 15 years, depending on the type and care they receve.
The electronic components,
being the most sensitive, will last anywhere between 3 and twenty
years.
Can I use renewable power to pump water from a remote
well?
Self contained remote
power systems for well pumping and remote communications have long been a cost
effective and reliable solution to a basic requirement. New advances in solar
pumps have pushed the range of these energy efficient systems to ever greater
depths. The offset savings on electrical
infrastructure offer an added value. Careful analysis of the options available
matched with the site conditions will provide the best return for your money.
