Traditional Solar PV Panels

Traditional solar PV panels make up the bulk of the solar market and today offer incredible value for money. Not only is the cost of initial outlay much lower than  ever before but PV starts saving you money right from the word go, silently, efficiently just getting on with its job. By generating your own energy not only will you immediately save on your bills but most systems will be eligible for the government Feed in Tariff scheme. Excess energy can be sold back to the grid if not used on site or channeled into heating uses such devices as the solar iBoost.  Where else can you invest your money and hope to see such good returns?

Due to their mass production costs are far lower than more bespoke modules and over the last few years prices for these panels that make up the bulk cost of any PV system have tumbled. While panel shapes and sizes have more or less become standardized in recent years, developments have seen power output increase while weigh has been reduced.

The key element of the panel is a silicone wafer which is a form of semi conductor. Two types are common, namely mono and poly silicone crystal. These are often identified by their colour and appearance with the poly silicone being made up of varying shades of blue pigmented wafer where mono tends to have no noticeable pigment and is darker in very generic terms.

Where economy is required such as in agricultural or commercial applications poly crystalline panels with natural silver grey aluminium frames are chosen. Now a days, more and more domestic installations are choosing mono crystalline panels with black frames to enable them to blend in more closely with weathered roofs of dark clay tiles or slates.

Conventional mounting systems typically have a 2cm gap between panelsAll Black

Appearance can be further enhanced by the choice of mounting frame employed which can be black to match and for new builds a neater and quicker way to install panels is to use an “in-roof” mounting kit that sinks conventional panels into the roof almost flush with the outer roof covering itself rather than using a conventional “rack” mounted kit that sees panels sitting on top of the covering. Other panel types exist and deciding which panel type to choose needs careful consideration.

To get the best out of the panels, the inverter, (which is the piece of equipment that changes the DC current produced by the panels into AC current  used in the home), has to be chosen with care. Inverters can optimise the performance from panels, coping in varying ways with differing light and shadow. Careful design, quality ancillary components and cabling quickly maximise returns for the shrewd investor.

At Oakwood, we don’t have a stock of panels and inverters waiting to be cleared from stock onto any customer’s roof regardless of its circumstances. At Oakwood we design systems and fit panels and inverters according to customer needs and the situation, for example, certain panels are better suited to straddling an East/West facing roof than others that excel when facing due South.

We like to provide customers with a choice of quality designs across various price points from house hold names such as Panasonic, LG, Sharp and SMA. We explain our reasoning for selecting each combination, providing technical information to enable customers to reach an informed decision according to their needs and budget.  We try hard not to be beaten on price despite offering this bespoke service.
