Solar Note: To be an effective passive solar heat collector the sloped roof, or skylight, must be within 45º of true south and have a minimum 4/12 (19º pitch), or too much reflection will occur in the winter. See General Solar Info

Solar Greenhouse Note: Greenhouse designs that incorporate maximum south facing glazing (and minimize east, west and north glazing) will reduce the light levels your plants receive. On these designs use Softlite Corrugated or Softlite 8, 16 or 25mm, at least on the roof, to defuse the light and maximize plant growth.
