Renewables

Solar PV

In the first place, Solar Panels remain the most popular method of self-generation for renewable electricity. That’s despite the Feed-in-Tariff ending. To be sure, they’ll have an immediate positive impact on your grid energy use and profits.

Coupled with fast ROI and years of bottom-line benefit, Solar panels will almost certainly outperform money left in your bank. Another key point is that there are many great finance options available. With this in mind, an IU Energy finance partner may be able to help.

What sizes do you install?

IU Energy chiefly installs commercial Solar Panel solutions for small to large businesses. In addition, we conduct community energy projects and some larger domestic installations. Overall, we specialise in roof and ground mount projects up to as much as 1MW.

Increasingly, not only do our Solar PV projects include battery storage technology, but also electric vehicle charging stations. In addition, we are OLEV approved for commercial EV charging applications. OLEV is part of the Department for Transport and the Department for Business, Energy & Industrial Strategy.

No subcontractors

IU Energy is by and large different from most competition. That is to say, our in-house expert engineering team conducts all works. To emphasise, this includes design, civils, electrical, control systems, metering and aftercare/servicing.

For this reason, we’re frequently winners of local and national awards, such as the TELCA ‘UK Energy Consultancy of the Year’.

What are the best brands for Solar PV?

The first thing to remember is that IU Energy uses Solar PV brands selected for reliability, longevity and product range. Furthermore, our Solar PV, panels must be from Tier 1 manufacturers and benefit from extensive warranties.

Indeed, in general this applies in this case to all our renewable and energy saving brands. 

Specifically, for Solar PV, there are two clear winners.

  • BYD for commercial Solar PV
  • LG for domestic applications.

BYD for example are a hugely innovative company with a long history in Solar PV. They also supply extended panel product and performance warranties.

LG on the other hand, guarantee 80% minimum output from their panels after 25 years. Furthermore, they supply two warranties.

  1. Performance over time 
  2. Quality of manufacture.

In other words, the panels will perform long term, despite working in harsh environments.

Likewise, for inverters we use three manufacturers.

  • Solax
  • Solis 
  • Fronius

Each has benefits depending on the application. Solax for example offer a 10-year warranty. Fronius features intelligent export limitation for installations which may occasionally exceed grid limits.

Below are case studies for projects we have conducted in commercial electricity self-generation using Solar PV, followed by FAQs.

FAQs

We have been fitting Solar PV for 17 years and our Solar PV panels, inverters and mounts have been chosen through the experience of fitting thousands of them. We only supply Solar PV with long warranties, proven reliability, continuity of supply, efficiency and great after-sales support. To ensure this, IU Energy only uses Tier 1 manufacturers. Tier 1 is defined by 25-year warranties from companies who are likely to be around for that time. The classification means that they must manufacture their own panels (no outsourcing), must be recognised on Bloomberg and must manufacture a minimum number of panels per annum. We call this ‘bankability’.

Yes. IU Energy can design a solar array with panels that provide an additional 20% output per panel for the same surface area of their standard counterparts.

Generally, yes. Providing the structure is sound we can spread loads very effectively, considering other factors like direction and wind. The suitability of any site is assessed during our initial survey. Ground mounting may also be an option.

Yes. Examples are former agricultural land and for applications like Community Energy, or where roof structure limitations/orientation cannot be overcome.

The amount of electricity a solar panel produces depends on three important factors: the size of the panel, the efficiency of the solar cells, and the amount of sunlight the panel gets. These days, most solar panels are about 5.5’ tall and a little more than 3’ wide. Modern panels of this size are rated to produce anything from 250 watts to 360 watts output. If a 250w panel received full sun for one hour, you’d get 250 watt-hours of electricity. With 4 panels, you’d get a kilowatt hour (1 kWh).

This is dependent on several factors including number of panels and roof mounting. The best way to determine your likely costs is to contact us for a site survey.

Yes. Grid energy is only an upward trend in cost and Solar PV reduces your demand and consumption. Add high-efficiency battery storage and you can continue to use what you generated at night. You will also still be able to sell your excess to the grid.

Six years on average, although we have many clients who achieved 4.

It reduces generation but doesn’t negate it and there are things that can be done to overcome it.

Yes, but there are ways of overcoming it. There are automated panel cleaning systems and bird deterrents. This challenge should not put you off any more than the thought of cleaning windows would stop you fitting them.

Optimum is 30-35 degrees. There are other mounting options however. 

It depends on the space available and you’d need a new inverter.

We’ve been around for seventeen years and are one of the oldest UK energy companies still in business. However, you also have the benefit of Tier 1 manufacturers’ warranties and insurance backed warranties.

The inverters we use connect by wi-fi to a router – it’s just a matter of logging in to monitor performance.

Yes. However, the inverter and installation need to be prepared for battery readiness.

We do it for you.

The simple answer is yes, a solar installation will charge your electric vehicles just as it will supply energy for the rest of your business. Even a small solar panel array with only 10 solar panels can provide enough power to charge a vehicle’s battery. Adding battery storage to this simply extends the useful hours when you can recharge an electric vehicle.
