The total cost of installing a photovoltaic (PV) system on a roof is a combination of many different expenses. These costs include the system design and engineering, solar panels, inverter, monitoring equipment, logistics costs, mounting hardware and labor. Other expenses, such as permits and inspections, will add to the overall cost.

Calling all installers, contractors and DIYers!
Exposed-fastened (EF) roofing covers a lot of territory – from agricultural and industrial buildings to commercial and residential properties. Sometimes called through-fastened, screw-fastened and face-fastened, EF roofing is a popular choice thanks to its reasonable price and long lifespan.

One of the most important aspects of any solar PV installation on a metal roof is wire management, but even seasoned professionals can find this task confusing. There’s a myriad of things to track. You need to position the conductors so they correctly connect as modules are installed, keep all wires off the roof, deliver jumpers to the homerun and down to the inverter, and stay organized. If you have a large-scale job, this process becomes increasingly complex.

When it comes to attaching solar modules to metal rooftops, traditional rails have been a conventional choice. But familiar concepts don’t necessarily deliver the best outcomes, and the advantages of rail-less solutions are moving the industry in a new direction.
Decades ago – when interest in mounting solar PV on rooftops began – the introduction of using continuous aluminum rails as a solar racking system to mount PV modules in place was a practical application for all roof types. Eventually, innovation opened new doors and rail-less solutions were developed specifically for metal roofing. Using discrete hardware to directly secure each module to a metal roof, the new strategy completely bypassed the need for rails and brought some clear improvements.

If you’re thinking of putting solar PV on your metal roof to generate renewable energy and save money over time, you’ve made a great choice. Metal roofs are an ideal platform for mounting solar modules thanks to their long service life and durability. Solar arrays have a service life of 35+ years, and metal roofing has a demonstrated service life of 60 years. Aside from metal, there are no other roof types that measure up to that without requiring replacement. Both standing seam and exposed-fastened metal roofs support solar arrays very effectively.

Did you know that your roof already comes with free rails? You can mount PV directly to the roof panels themselves - using the “direct-attach” method. Whether you are dealing with standing seam or ribbed, face-fastened panels, these metal roofs have one thing in common: They all have built-in rails.

When it comes to sharing solar array costs, companies often shy away and dance around the question. They usually focus on the customization angle – telling you that prices vary, and that this is what makes estimation difficult.
Now, of course costs vary, because no two projects are the same but whether you are an installer, contractor, or a homeowner, you share two common questions:

Photovoltaics (PV) is the process of converting light into electricity. PV technology converts sunlight (otherwise known as solar radiation) into direct current electricity. This process uses semiconductors, (the most common semiconductor material being crystalline silicon), so when the sun hits the PV, the electrons are released and form an electric current.
