Renewable Energy FAQs

Solar PV

Why choose solar PV?

Solar PV stands for Photovoltaic (light/electricity). This is an added value product and should help to create more value for your business.  We can also help you to reduce your electricity costs whilst improving your carbon footprint.

What does 1 kW mean? How many solar PV panels would this be?

Each panel is 1.6m2 (1.6mx1m).  1kWp therefore is 6.4m2.  1 kW is 4 panels. 

50kW = 320m2 (Tennis court is 262m2)

100kW = 640m2 (Tennis court including run off etc 650m2)

250kW = 1600m2 (Bowling Green 1475m2)

500kW = 3200m2

1MW = 6400m2 (Rugby Pitch)

What would be a ‘High electricity user’?

High electricity in comparison to roof size:

50kW = £3k per annum + (Warehouse, small factory, care home, hotel)

100kW = £6k per annum + ( Medium manufacturing facility, cold storage, large warehouse, FLTs)

250kW = £15k per annum + (Larger scale manufacturing, cold storage, chilled distribution, large warehouse, bakery

1MW = £30k+ (Significantly sized manufacturer/warehousing with robots)

What is an average Payback period?

Payback in as little as 6 years.  Very low risk investment.  Additional benefits include sustainable credentials and protection against rising electricity costs in the future.  A planned scheme enabling the system to be ‘taken with you’ has been announced.  It will add value to your business – a building with an income stream from the utilities

Biomass

What is the RHi?

The Non-Domestic Renewable Heat Incentive (RHi) is a Government environmental programme that provides financial incentives to increase the uptake of renewable heat. For the non-domestic sector broadly speaking it provides a subsidy, payable for 20 years, to eligible, non-domestic renewable heat generators.

The Non-Domestic RHI is open to the non-domestic sector including industrial, commercial, public sector and not-for-profit organisations with eligible installation. In the context of the scheme, a non-domestic installation is a renewable heat unit that supplies large-scale industrial heating to small community heating projects.

This includes for example small businesses, hospitals and schools as well as district heating schemes such as where one boiler serves multiple homes.  All applications are subject to the detailed scheme rules.

For further information please visit the www.ofgem.gov.uk website. Ofgem is responsible for implementing and administering the scheme on behalf of the Department of Energy and Climate Change.
What size boiler do I need?

This depends of your current/future heat demand. Our in house design team can calculate this if you can provide some detail on your heat use (kWh per annum or oil/lpg bills for the last 1, 2, 3 years). How much of this heat requirement is from Sept – April? The more information you can provide, the more accurate heat profile and hence the more accurate the boiler sizing and system design.

 

What should I burn – chip or pellet?

This depends on a number of factors:

  1. The likely boiler size – if relatively small, then likely to suit pellet rather than chip (199kW or smaller);
  2. The available space for fuel storage – chip is a bulkier product and therefore requires larger storage capacity/volume. 
  3. Availability of fuel – pellet is more readily available since it can be transported further distances.

Please note fuel must be BSL registered to claim RHI payments.

Can I burn my own fuel?

Yes, but you must register on the BSL register.

 

Can I install (and avail of RHI on) more than one boiler per site?

Yes; provided the heat being produced has a use.  However RHi applications will only be approved on one boiler per heating loop/circuit.

Is there much of a maintenance requirement for a biomass boiler?

This is dependent on the size and type of installation as well as the operational hours, but it should be noted that there is a higher maintenance requirement with a biomass boiler than gas/oil equivalent.  As a rule, some basic maintenance and cleaning is required monthly (or every 6 weeks) while boiler is in use.  Flogas Renewables offer a range of maintenance services that can be tailored to meet the end users requirements. We have nationwide coverage and can offer out of hour’s technical support over the phone.

What support services do Flogas offer?

Flogas currently process and supply over 30,000 tonnes of biomass annually across a range of installations size to a variety of customers.  In addition we offer a range of maintenance services that is often provided as a combined fuel and maintenance agreement and sold through the heat meter (£/kWh).  This solution is most favourable amongst our customers as it means the end user only pays for heat used, and is not subject to efficiency issues with the boiler or at the mercy of the fuel quality being delivered.  Flogas assume entire responsibility for the delivery of heat and system performance.
