Is My Home Suitable?
From our experience over the years, the vast majority of houses are suitable for solar panels. We pride ourselves on honest, reliable, & highly professional service. If your roof, or property is not suitable, we will definitely tell you, and have advised customers of this in the past. We rely heavily on delighted customers for recommendations, and so would not want you to spend your hard earned money on something that would not work as expected.
A site survey will take between 45-90 minutes, dependant on the questions you have. We will evaluate the points below, take various measurements, need access to the loft if possible, and the fuse board / consumer unit. Whenever possible, we will bring you an estimate based on Google Earth measurements, so we can provide you an accurate estimate. We will go through the cost and benefits together in the estimate. We will never ask you to sign on the day. We will listen to your preference if you have any, regarding equipment, any brands you may prefer, and send you a bespoke and detailed quotation within 2 working days. We don't stack them high, and sell one solution. We strongly believe in providing a tailored solution to your needs and preferences. Bespoke service yes. Inflated prices no. Midori Solar are always price competitive.
Of course some roofs are smaller than others, and we have installed as few as 5 high efficiency solar panels on a home due to roof windows. Prices start from £2700.
As the efficiency and technology of solar cells continues to rapidly improve, there are typically several high quality options depending on a client's needs, and budget. The most popular solar panels now range between 250 - 285 watts each.
The main factors affecting the performance of a solar PV sytem are:
- the direction the roof faces. This is one of the most interesting, and perhaps misunderstood areas about solar panels. It is true that a south facing roof will generate more electricity, than an east or west facing roof, typically about 20% more. This means that in terms of feed in tariffs, you will be paid more for the electricity you generate since you produce more electricity in total, per year. Most of the electricity is produced in the hours around mid day (think of a bell curve in terms of the solar electricity production). However, in terms of electricity savings from solar power, savings can often be significantly greater for an east / west split solar PV system. Why? Most of us use more electricity in the morning or evening, when getting ready for the day ahead, or cooking family meals, doing laundry, tumble dryer, dishwasher etc. So an east / west split (or south / east, or south / west) can produce more electricity when you use it most, saving you more money. It truly does depend on individual household demand, and flexbility to some degree. These days, with smarter appliances, you can delay start to a time when you can maximise your usage of free solar electricity. Feed in tariffs + savings = total benefit from a solar PV system. Learn more about feed in tariffs, in our cost and benefits section.
- How much shade is there on the roof? In most cases, a roof will not be heavily shaded. Things like trees, and aerials, can usually be easily managed, or re-located. Even a redundant chimney can be removed affordably, often as part of the solar installation. If there is shade, it's worth having it evaluated by a professional. Why not get in touch for a free survey and consultation? For "stubborn" shade, in most cases, it can be effectively mitigated thanks to relatively new technology such as optimisers, or micro inverters. Don't let it worry you, a free assessment is just a friendly phone call away.
- The roof pitch (roof angle). Most roofs in the UK have an near optimum roof pitch.
How long will solar panels take to install? Usually 1 day, possibly 2 depending on weather. Scaffolding is usually erected a couple days prior, and removed 2-3 days after the PV installation.
Since the highest feed in tariff rate applies to PV systems less than 4 kw, it's usually most cost effective to install as close to this limit as space safely allows. The reason being, many of the costs of fitting solar panels are fixed: scaffold , electrician, testing, even roof works to some degree, remain nearly the same whether installing 8 panels or 16 panels. So a bigger system tends to be better value; it will usually provide the shortest payback period, and highest return on investment (feed in tariff payments + savings combined). Sign up to our newslestter or request a call back from our home page to find out more. So if you don't have room for 16 panels on one roof, don't worry. It's more and more common to install higher output solar panels, on 2 sides of a house to achieve this, and maximise your investment with solar PV.
