A solar collector was installed on the White House's west wing this summer, and while proponents of solar power say the Carter Administration has given them some support beyond the symbolic gesture, they're impatient for more.

A coalition of environmentalists, public interest groups and solar industries known as the Solar Lobby has published a report called Blueprint for a Solar Society. (It has 40 pages, costs $2 and is available from the Solar Lobby, 1208 Connecticut Ave. NW, Washington 20036.).

The United States could become a "solar Society" within 50 years, the report noted, but incentives are necessary to implement that. On the housing scene, the group calls for federal tax breaks and loans to spur solar development.

Among the recommendations are:

A solar bank, the function of which would be to give long-term, low interest loans to homeowners who want to install solar systems.

Allocating $100 million per year over three years to convert public housing.

A 20 percent increase in multifamily mortgage insurance and assistance programs of the Department of Housing and Urban Development and its Federal Housing Administration.

A 40 percent tax break for developers who build new houses that incorporate solar features.

If all those steps were taken, the report said, fuel bills in 80 percent of all new construction could be 40 percent lower than in 1975-76. By 1990, 85 percent of all new buildings would save 60 percent, and by the year 2000, 90 percent of all new buildings could enjoy energy savings of 80 percent.

The solar bank proposal is now before the House Banking Committee. The bank would function under HUD'S Government National Mortgage Association and would offer 30-year, 3 percent loans for owners of residential and commercial buildings to buy solar systems.

The bank's supporters think a subsidy is necessary to overcome the economic disadvantage solar energy now suffers. Under present policy, they say, tax advantages to conventional energy such as oil and natural gas will amount to about 150 times those provided to solar energy by fiscal 1980.
