Solar Hot Water Considerations
- A larger water tank can take compensate for a cloudy day causing lower solar water heating.
- Size the solar collector for your hot water consumption and average daily solar radiation.
- The best aspect for solar panels is facing the equator (Northern hemisphere face south, Southern hemisphere face north).
- The ideal pitch angle equals to your location latitude.
- Special considerations are needed in frost or snow areas.
- Instantaneous gas heating can be used after the hot water tank to make up any shortfall in water temperature.
- Become familar with any government rebates available. E.g. $1600 is available in Australia.
- Renewable Energy Credits (RECs) can be sold after installation of solar hot water in some countries (~$1000-$2000).
