This document from Edge Electrical & Renewables Ltd describes various renewable energy technologies available for commercial installations including solar PV panels, solar thermal panels, heat pumps, wind turbines, biomass boilers, mini hydro, LED lighting, and rainwater harvesting. It provides details on how each technology works and the associated benefits such as reducing energy costs, generating income from feed-in tariffs, and qualifying for government incentives. Edge Electrical offers commercial customers installation and long-term monitoring of these renewable systems to lower energy bills and gain tighter control of site budgets.

10. Mini Hydro
 What is it and how does it work?
 Bespoke dependant on case
 Benefits
– Virtually constant power source

11. Rainwater Harvesting
 What is it and how does it work?
– Rainwater is reused and treated for either
potable or grey water use
 Benefits

12. LED Lighting
 Major savings in energy and running
costs
 Minimise maintenance frequency &
costs
 Diversity in design and specification

13. Feed In Tariff (FIT)
Typical Example Of Benefits With 20 kWp Solar PV System:
 A. Generation income
Tariff 13.03p per kWh
x Annual generation 18,000 kWh = £ 2,345.40
 B. Export income
Earn 4.5p x (estimated at 50% of generated amount) kWh = £ 405
 C. Fuel bill savings
Save 10p per kWh x 17,000 kWh = £ 1,700
Total system benefit per year A + B + C = £ 4,450.40

14. Solar (PV) Panels
 Typical Investment & Payback 20 kWp Solar PV System
 Installation cost (£ 32,000) / Annual benefit (£ 4,450.40)
= 7.2 year payback on investment
 The Feed In Tariff lasts for 20 years & all calculations are
made without inflation adjustment (which will be made) and
increased imported electricity costs. Therefore the benefit
total is likely to be considerably more.

15. Government Incentives
Available
 Feed In Tariff (FIT)
– Available to all
 Renewable Heat Incentive (RHI)
– Available to commercial
 Renewable Heat Premium Payments
– Available to domestic prior to RHI roll out this
summer
 Enhanced Capital Allowance (ECA)
– 100% of investment written off in year 1

16. Other Incentives
 Independent Low Interest Loan
Siemens Financial Services (SFS)
(Previously run by Carbon Trust)
– No capital outlay
– No additional outgoings (Savings made
pay for the installation)

17. Why Choose Us ?
 We will help reduce your running costs on site with our expert knowledge and installations.
 Our installations are MCS approved so are eligible for government grants including the
‘Feed In Tariff’ and the ‘Renewable Heat Incentive’
 We never ‘fit and forget’ any of our installations and continue to provide a premium on-going
service to our existing customers by helping to continually reduce consumption.
 We will show the energy consumption reductions by energy monitoring Pre & Post Installation
to confirm that we have achieved or outperformed our energy reduction estimates.
 We can continue to monitor your site remotely to ensure that your plant is running efficiently
with minimum downtime.
 We can provide site consumption figures to give you better control of budgets and site costs.
 We can provide access to low interest finance for your project reducing capital outlay (savings
made cover the majority of loan repayments).
 All our work comes with a 10 year insurance backed warranty. The solar panels we use come
with a 25year output guarantee which is European insurance backed should anything happen to
the company.
 We offer a free system performance check at 12 months to ensure that the system is running
to its maximum efficiency.
 With every installation we also make a donation to UNICEF.
