How do I attach solar panels to my shingle roof without causing leaks?
avwFm87mDz2011-04-01T15:13:00+00:00Our ConnectMaxx roof hooks are designed for any roof. We suggest that each be attached directly into a rafter using two Simpson Strong-Drive screws. Roof caulk can be used to seal these penetrations. (One installer we know used butyl rubber.) Our concave X-mount flashing then fits securely over the roof hook and under the shingles for a weatherproof connection. All of our collectors can be mounted using these roof hooks.
How well will my collectors perform if they are not positioned perfectly?
avwFm87mDz2011-04-01T14:56:58+00:00Fortunately, solar thermal collectors are not nearly as sensitive to light conditions as PV collectors. As for performance, you have roughly a 60 degree window of opportunity to mount the collectors toward south before you begin losing a small bit of total production. In other words, your house can be situated 30 to the east of true south or 30 degrees to the west of true south and your performance will still be at or above 95%. As far as tilt angle goes, this window opportunity is slightly smaller but still you can have a roof pitched about 20 degrees plus or minus of your particular latitude angle and you will still see results at or above 95% of expected. Ask a Sunmaxx rep to run a Polysun report for your particular conditions to be sure, you will be happy you did and pleasantly surprised.
Can I tie a solar thermal system into my existing system?
avwFm87mDz2011-04-01T14:49:01+00:00Yes, you sure can. There are very few systems in the US that will not accept a solar thermal upgrade, The only exception would be a steam system. Whether you have forced hot air, boiler with baseboard, sub-floor radiant, in-floor radiant or wall heaters you can very easily integrate a solar thermal system upgrade. We have systems that are designed for every possible option for you, the only question is- are you ready to start saving money and lower your carbon footprint?
Simulating Performance of Solar Thermal Systems
avwFm87mDz2011-04-01T14:27:20+00:00Solar thermal systems will behave differently depending on a few variables such as, the obvious, location but also angle of tilt (slope off horizon), orientation angle, temperature of inlet fluid and also daily ambient temperature. We can calculate the efficiency of collectors for various times throughout the day but given the dynamic nature of production vs. consumption, it is better to use simulation software to accomplish this. At Sunmaxx, we use Polysun Simulation Software . By using this software, we can very easily ascertain the estimated performance during the course of the year.
