Why Essex households choose REST
From Thames-side towns to estuary villages, Essex roofs differ widely. The estimate starts with your bill, and the quote with your roof.

Eurener's manufacturer warranties on NEXA panels run for 30 years on the build and 30 on output. Storage from any of four makers (Duracell, Fox ESS, Tesla, Growatt) is added only where it earns its place.
MCS-certified work, a deposit insured through HIES, and savings that EPVS checks and clears before the install is allowed to go ahead.
Essex customers
Two Essex installs, and what they are estimated to do for the household bill.

Case study
Daylight is free. The trouble is that a household's busiest hours often come after it has gone. Khandaker's Thurrock home was set to spend £1,750 a year on electricity, from 7,000 kWh.
Fourteen panels collect the daylight and a 10 kWh battery holds a share of it back for the evening. Half of the electricity the roof produces is projected to stay inside the house, so the system spends most of its energy where it matters.
It is a patient investment: payback is projected at around 12 years. What comes after is the point, and the figure below shows how the savings could stack up over 30 years.
*Assumes electricity prices rise 7.04% a year. A projection, not a guarantee.

Case study
Saulius's Essex home was set to spend £2,291 a year on electricity, £191 a month, from 8,500 kWh. A household that uses that much power does not need a roof built to sell it.
So this one is not. Roughly 71% of the 13 panels' output is projected to go straight into the home, and two batteries hold some for later. Exports play a small part in the projection. The roof is there to run the house.
Seven years is the projected payback, among the shortest of any install on these pages. After it, the roof is still doing the same job for the same busy household, and the 30-year projection below shows where that leads.

What it means at home
A solar system keeps contributing long after its first year. Looking across the forecast helps you compare years of grid bills with the value of your own generation.
Switching on the washing machine around lunchtime can mean it runs on the roof's power rather than the grid's.
A battery lets the evening meal and the bath run on stored sunshine instead of on power bought at the end of the day.
Once the system is paid for, the power it makes costs you nothing extra to use, which also shields part of your usage from price rises.
Why you can rely on the figures
REST would rather you verify these than simply believe them.
Eurener backs the panels with manufacturer warranties of three decades, one on the build and one on output, and REST will help you claim if it comes to that.
Duracell, Fox ESS, Tesla Powerwall and Growatt, with capacity chosen around when your household draws power.
HIES backs your deposit with an insurance-based scheme, up to the limits it sets.
Savings are worked out with the EPVS calculation, checked and cleared by EPVS first, described as estimates, and listed with the assumptions used.

Solar in Essex
Three practical points for Essex homeowners.
Towns such as Colchester, Maldon and Saffron Walden have conservation areas, and listed buildings need separate consent. In those places, check before fitting panels to a wall facing the road. Elsewhere, an ordinary house roof can generally take panels without an application.
Most of Essex connects through UK Power Networks, with some outer-London edges covered by neighbouring areas of the same company. REST makes the G98 or G99 request on your behalf, though the operator decides how soon it answers.
Seaside terraces face wind and salt, 1930s suburbs have broad pitched roofs, and newer estates offer neat, regular slopes. The surveyor measures your own roof and shade before proposing anything.

Common questions
Nothing. A quote carries no commitment to go ahead.
Prepared for your roof and usage in Essex. It includes:
REST has finance options, including ones with no upfront cost. Finance is subject to status and lender approval, and REST UK acts as a credit broker, not a lender.
Yes, to turn an estimate into a firm price. A surveyor measures the roof, notes any shade and checks the electrics, at no charge.
It starts from an average household with your bill. The quote then swaps in the facts about your property, though it remains an estimate.
It can be. Once a system is paid back, the power it generates for the house stops costing you a supplier's price, and your proposal sets out how long REST expects that to take.
They need more attention to wind and salt exposure, which affects fixings and equipment choice, but they are not a barrier. The surveyor allows for it.
Not always. The answer turns on how much power the household draws once the sun has gone, and the quote compares the options.
Yes, provided you join a Smart Export Guarantee scheme. Each supplier decides its own rate.

Projected net savings over 30 years: Khandaker A, Thurrock, Essex. This is the projection in the customer's own proposal, after the cost of the system and any finance repayments. It assumes electricity prices rise 7.04% a year, panel output falls 3% in the first year and about 0.52% a year after that, battery capacity falls 2.5% a year, and the battery (£1,000) and inverter (£750) are replaced every 10 years.
Projected net savings over 30 years: Saulius A, Essex. This is the projection in the customer's own proposal, after the cost of the system and any finance repayments. It assumes electricity prices rise 7.04% a year, panel output falls 1% in the first year and about 0.38% a year after that, battery capacity falls 2.5% a year, and the battery (£1,600) is replaced every 10 years.
If electricity prices rise more slowly than assumed, the savings will be lower. Projections are not measured results or a guarantee, and they depend on the roof, usage, tariff and future energy prices. These are selected examples, not typical results.
