With Bristile flat tiles in either a ceramic/terracotta or concrete range.Īccording to the manufacturer, the solar efficiency of the tiles is on par Warranty that guarantees their structural integrity and a 10-year total roof warranty for the system.Īustralian company Bristile Roofing is due to complete its first solar roof Bristile solar roof tilesĬost: $15,675 (4kW of Bristile solar tiles with inverter)įull power-generation capabilities. But, as with all technologies, once their scale of production increases the cost should fall. The average cost for a fully installed 4kW solar PV system inĪustralia is $5697, according to data from solar PV brokers Solar Choice, which includes the cost of the inverter (see jargon buster).Īlthough tiles are pricier than solar panels, it's likely they'll remain attractive to high-end, architect-designed houses with slate- or ceramic-tiled roofs. To create a level playing field, we picked a 4kW system as a comparison point for price with the tile retailers below. Solar roof tiles cost more than the regular PV set-up. Solar panels, and in our strength and impact testing for hail damage, they often perform as well orīetter than conventional roofing materials. They're much more resistant to cyclonic winds than.They're not bolted onto the roof, so there's no extra.There's no need to drill holes in the roof to install them.Just like conventional solar PV panels, solar roof tiles can generate electricity to heat the water, run the appliances and cool the house. Your sunny roof area is the wrong shape or size for conventional PV.Your north-facing roof area faces the street.Prevents the installation of solar panels. You live in a heritage conservation area that.You value the aesthetic of clean roof lines.Read solar panels review Why consider solar roof tiles? We should really have a grid-connectd system like this where you could buy a share in such systems and get an appropriate share of the power generated off your electric bill, but I'm sure the middlemen and politicians would ruin that idea.We've tested to find you the best. It would be much better to spend that amount of money putting solar panels on the roofs of commercial buildings like warehouses, shaded parking in large parking lots, etc, or stand-alone solar farms. Even with all that, I think it's still probably a somewhat good idea, just not as good an idea as the solar salesman says it is.Īs a society, home solar is a poor way to spend that amount of resources. And take bribes from the fossil fuel industry as well. Then throw in anti-environmental Trumpanzees who think that windmills cause cancer and probably think that about solar as well. I don't know what you do if you need your roof replaced. Incentives at purchase change with which way the political wind blows, so that makes it harder to figure out the up-front costs. Wind power throws another uncertainty into that equation because it comes and goes, too, and is less predictable than solar. It's not that "solar is bad." It's just that you have to work with its limitations. It's actually a good thing if we're generating enough from solar that that becomes a problem. At some point, the solar users have to pay their fair share of the fossil fuel or nuclear power plants to keep the grid up. Even if you have a lot of solar, you need reliable 24 hour power to keep the system going. There is also a long term problem with economics as solar becomes a bigger share of the total grid power. If electric rates go up in the future, your payoff is probably better, so that's a plus. Even in the "green" states, a lot of the agreements in terms of how you get paid or charged for power keep getting adjusted to screw the people who already installed solar. Unfortunately, you can't trust them to live up to their agreements long term. Some pro-solar political people are trying to make it easier with incentives and favorable terms for how power is bought and sold. What's particularly hard to plan for is the politics involved. Many of the installation contractors are dishonest and incompetent. I'd be very leery of the fine print of the systems you end up not owning outright or that have financing through the electricity generate. I think a lot of the solar power salesmen are people who weren't honest enough to work as used car salesmen, so watch out for that. Most people don't have the long term economic outlook to make it really worthwhile.Īlso realize that 90% of the home solar installations don't provide power if the grid is down, not even when the sun is shining. Probably a good idea, but not a clear choice either way economically at the moment.
