Why invest in Renewables?

• By 2015 it is estimated we as a planet will be using more fuel than we can produce.
• Reduce your Carbon footprint.
• Reduce your effect on the planet and climate change.
• Reduce your reliance on grid supplied power which may be fuelled from gas or oil from abroad with no guarantee of a stable supply.
• Reduce your fuel bills. Costs are inevitably increasing as fossil fuels eventually run out.
• Current government grants can provide households (including builders where the householder is as yet unknown) with up to £2500 (UK) or up to £4000 (Scotland) towards installing renewable energy systems, community projects with 50% funding, or a business with an interest-free loan. Visit the Energy Savings Trust (Scotland) or Low Carbon Buildings Program (UK).

Why Solar Photovoltaics (PV)?

• Solar Photovoltaics (PV) is the conversion of light into electricity.
• Only wind turbines, hydroelectric and solar PV generate electricity. All other renewables generate heat.

• If you generate electricity, any power you do not use is sold back to the grid or stored. Heat generators can only heat air or water and once it is hot the continuing heat generated is wasted.
• Of the electricity generators solar PV is silent, the easiest to install, has no moving parts and is the most efficient.
• Solar PV systems do not require any maintenance and have a working life span of 40 to 50 years.
• Solar PV produces NO greenhouse gases thereby considerably reducing your carbon footprint by 0.6kg per kWh generated.
• A 1kW Solar PV system in the UK should provide at least 750kWh of electricity per year. An average 3 bedroom home uses 3290 kWh per year. The table indicates how much of your electricity bill you could save depending on how big a system you install and what your current electrical usage is.  (See also the table at the bottom of this page):
  
  

  Current electricity use (from your bills)	1 kW PV System	2 kW PV System	3 kW PV System
  750 kWh	100%
  1500 kWh	50%	100%
  3000 kWh	25%	50%	75%
  3290 kWh	22.8%	45.6%	68.4%
  4500 kWh	16%	33%	50%
  6000 kWh	12.5%	25%	37.5%

• The grid supplier should install a free import/export meter for selling back generated electricity. The current system is based on ROCs and means the grid supplier pays for the total amount of electricity generated AND then pays again for the amount sold back to the grid.

• Stand alone solar PV systems are available but require battery banks and therefore add considerable cost to the system maintenance, as well as significant safety issues. However, Aissac can supply and install such systems where that is the best option.

Why Aissac Electrical & Solar?

Aissac Electrical & Solar are the First BRE (Building Research Establishment) Accredited Solar PV Installers in Scotland. Certificate No. MCS 1024.

We are also Members of the REAL Assurance reality check scheme - a consumer code for renewable energies regulated by the OFT. See REAL Assurance Scheme Website.

As members of the above organisations we one of the very few companies in Scotland at present that can provide our clients with access to the government grants for solar PV.

We provide a service which is fully tailored to our client's requirements and may include:

• A feasibility study for your property (please enter your details for a FREE assessment on the right)
• Guidance and advice on preparation including Structural Surveys, Planning requirements and Build Warrant applications

• A survey your property to design the most appropriate system depending on budget, available space and your energy requirements.
• Full system installation service including roof work and electrical work.
• Full system commissioning, including certification required by Build Control, the DNO (to connect to the grid) and Grant administrators.
• Two year warranty on all installation work.
• After-sales assistance in the unlikely event of a system failure.
• Ongoing Periodic Inspection Reports (PIR) as required (usually every 10 years) to ensure the continuing operational safety of your system.   Note that these inspections are advisable for all your domestic wiring in any case!

What is the cost of a PV system?

Aissac can locate any accredited solar PV product on the market and so can offer the best value systems available at any time. To give some idea, the following table shows an approximate cost of systems using two different makes of panels in four different sizes. These costs include an inverter, cabling and switching, design, installation, commissioning and certification:
