Solar Photovoltaic - WHY

How it works◦ You pay capital for installation

Depends on space and orientation◦ Electricity Suppliers pay

41.3p for EVERY unit you generate EVEN if you use it.

3.4p for units you do not use.

You get◦ Savings on your electricity bill – about 50%

If you change your habits◦ You get a ¼ ly payment based on what you generate.

Return on investment◦ 10% (20% tax payer) / 12% (40% tax payer)◦ Represents 8% interest◦ Inflation proofed◦ Guaranteed for 25 Years◦ Payback period – 8 to 10 years

Solar Photovoltaic – Feed In Tariff

Solar Hot Water Panels

I’ll be moving house in the next few years◦ Not worth investing – I won’t see the payback.

I don’t have the cash

I am maxed out on mortgage / loans / credit cards

What is the Green Deal ?

These Reasons are Countered by the Green

Deal

Green Deal Assessor◦ Produces a “Whole House Plan” ◦ Estimates the savings◦ Checks for a Pay Back of 25 Years (Golden Rule)

Green Deal Installer(s)◦ Make changes to the house based on the Plan

Green Deal Provider (Green Investment Bank?)◦ Provide the finance◦ Collect the payments via your energy bills◦ These pay off the loan◦ THE LOAN IS ATTACHED TO THE PROPERTY NOT YOU.◦ Likely to be limited to £6500.

Full Scale Refurbishment would save £8.7 billion/year on household energy bills

What is the Green Deal ?

Insulate◦ Cavity Wall◦ Roof – at least 270mm Rockwall / Glass Fibre◦ Thermally Lined curtains◦ Behind Radiators◦ Under Floor – if you can

Eliminate Drafts◦ Doors / Letter Boxes / Keyholes◦ Chimneys◦ Floors◦ Windows !!

Radiator Valves Set your Boiler Timer Condensing Boiler

◦ New Water tank ? Get dual coil Lighting – LED if you can

◦ Halogen – boo! Please Please Please Check your appliances !

◦ Upright Fridge / Freezer◦ Tumbler Dryers – Boo!!◦ Freezers◦ Check your PVR / Satellite boxes / TV on standby◦ Get an OWL Meter

Rob’s No-Brainers

Redecorating your sitting room ?◦ Make it an ECO Room

Consider internal insulation Under floor Insulation Install a wood burning stove – if you can. Draft proof the floor and doors Put in a mini heat recovery system for fresh air. Put insulation into the ceiling !

◦ Make it a ZERO ENERGY ROOM ! Solar PV – if you have the money or

◦ Which Report suggests increasing your mortgage. Make sure you have a long term plan

◦ Check that nothing else will be required when altering the room.
