Solar PV Roof Kits

Solar photovoltaic kits may allow a more straightforward installation and some savings in terms of costs.

This page is on solar PV (roof) kits for electricity production. For other types of solar kits, see:

- Prepackaged solar retrofits for gas and electric heaters

Advantages of solar PV roof kits

Solar photovoltaic kits are conceived for installation on existing roofs, and they are modular, flexible and easier to install. They also may allow lower costs than non-prepackaged systems.

Disadvantages of solar PV roof kits

Solar PV kits are scalable and modular, and they not present disadvantages over non-packaged systems. Be careful with lower quality kits: prefer well known brands or certified components, to get a higher guarantee of quality.

Components

Solar PV kits include the classical elements of any photovoltaic system: a set of solar modules (make sure that they are of good quality and reliable; see on this issue PV solar modules), an inverter, an electric meter, isolator switches, DC cabling and connectors, support framework and mounting hardware. They may include some options, namely wireless remote display and mounting brackets for specific types of roofs, and they may also include batteries for off-grid applications.

Mounting framework

Solar PV kits include (roof) mounting frameworks to allow a quicker and more economical installation. Usually the framework is built up above the roof (onto roof fixings) and there are several types of framework for use in several types of roofs. Modules are typically fastened to the framework from the front.

Installation

The standardization of prepackaged solar kits do not mean a DIY installation. Unless you have electric knowledge and experience, it’s better to deal with an accredited installer. Besides, he will help you with possible rebates and grants.

Warranty

The different components of the kit have different warranties: modules enjoy a typically wider warranty (20 or 25 year warranty is common). The inverters involves a typical shorter warranty (5 years is common).
