What do you mean reduce before you produce?
Sizing Solar Systems

Minimise, and its global solar partners produce detailed calculations of the energy produced by the PV system and matches it with the desired energy demand. The main parameter when designing a PV array is the load energy demand or energy usage in (kWh).

When describing a PV system in terms of components, it is logical to use the energy flow path from the array side to the load side. However, when sizing a PV system, due to system losses. it is necessary to consider the energy demand before considering the PV supply side. For that reason, PV system sizing starts at the load side and proceeds backward to the PV array side.

Reduce before you

Before performing these calculations Minimise deploys its energy monitoring system to attain the base line energy use of the building. Using IPMVP protocols, along with at least 12 months of energy bills Minimise can graph the client’s energy usage.

The Minimise EEM real-time data does what a utility bill can’t, using the Minimise Analytics platform, it shows you exactly how your energy is being used. The information is displayed in a language you will understand, be it kW’s, Cost or Carbon. Now you can monitor individual pieces of equipment, isolate energy leaks, expose energy abusers.

Using this information Minimise can deploy its vast array of energy saving technologies which will reduce your overall energy consumption, often by 20% or more which of course will reduce the size of the solar installation. Alternatively, you may wish to use batteries to store excess energy for later use, or perhaps, incentivise employees by providing free (or cheaper) EV charging.

Minimise is technology agnostic and always deploys the best available
technologies as it strives for excellence and complete customer satisfaction.

Not all clients/sites are ready to accommodate PV arrays. That can be due to one or more of the following factors:

  • Space availability for the PV array (roof/car port area?).
  • Unsuitable site conditions (restricted sun)
  • Local rules governing the export of power to the public grid.

Before designing and installing a PV system, it is important to make sure that the site is suitable for installation by considering the following factors:

  • Shade-free, sites are best performing when there is no shading on the PV array,
  • South-facing. In the northern hemisphere, the sun path is generally leaning towards the south. The opposite applies to the southern hemisphere where the sun appears to be towards the north.
  • No obstructions. Sites need to have minimum obstructions before installing PV arrays. Obstructions may include chimneys, gables, and HVAC units on rooftops.

Of course, sometimes it’s easier to talk to the experts who knows how to size a solar system and can assist in the design process and ensure the system works within your constraints (budget, finance, build space, storage and grid connection).

The fastest way to get a thorough evaluation of your solar needs is to contact us and connect with our team. We’d love to help you design the perfect system to meet your solar requirements.

Budget and Finance

Budget is an essential factor that plays a huge role in the design process. It varies with design limitations. available tax rebates and incentives at each location and of course the cost of power from the grid.

Many businesses face financial challenges and often don’t have the necessary financial outlay to consider purchasing solar despite understanding the benefits it would bring. Minimise has many years’ experience in such projects and can help provide both the financial tools and the technical expertise to enable these types of projects to get done using their MVP (Measurement and Verification Partnership) agreement or their NCOPA (No Capital Outlay Partnership Agreement).

    Meet Andy


    Senior Technical Director

    We get asked a lot of questions about the @Minimise Global approach, and when the questions are technical we always ask Andy Smith, our Senior Technology Director. Turns out, Andy has quite a bit of great information for the common energy efficiency bloke or the super technical engineer or tradesman. So we created Ask Andy. Since we made it a cute cartoon, here is a little background to make sure he truly exists in real life.

    In his words…

    Married with two grown up girls.
    Living on the north coast of Cornwall.
    Well-travelled Electrical Engineer 30+ years experience.
    Worked on both industrial and commercial energy saving projects, large and small, all over the world.
    Headed up the lighting portion of the largest zero cost energy saving project in the world.
    Product designs include three single and three phase motor controllers, variable speed drives and high output  industrial LED fixtures.

    Hobbies include restoring vintage British and Italian motorcycles, touring and Motogp.

    See, he is real!

    So anything you want to know just Ask Andy and chances are he’ll give you an answer that he ponders on a motorcycle somewhere in an English countryside. Or in the locaa pub. Cheers!
