Item 3. Source and Amount of Funds or Other Consideration

On August 23, 2006, Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) entered into an Agreement and Plan of Merger, as amended by that First Amendment to the Agreement and Plan of Merger dated October 4, 2006, the Second Amendment to the Agreement and Plan of Merger dated December 1, 2006 and the Third Amendment to the Agreement and Plan of Merger dated December 21, 2006 (the “Merger Agreement”) with Solar Power, Inc., a California corporation (“SPI”) and Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) wholly-owned subsidiary, Welund Acquisition Corp., a Nevada corporation (“Merger Sub”). Effective as of December 29, 2006, pursuant to the Merger Agreement, the Merger Sub was merged with and into SPI, with SPI surviving as Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) wholly owned subsidiary (the “Merger”). The Merger was consummated on December 29, 2006, pursuant to which SPI became Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) wholly owned subsidiary. In connection with the Merger the Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) issued an aggregate of 14,500,000 shares of restricted common stock to the existing shareholders of SPI. Each share of common stock of SPI was cancelled and exchanged for one share of the Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) common stock. As a result, Mr. Kircher, our Chief Executive Officer and Director who, at the time, was also the Director and Chief Executive Officer of SPI, became the beneficial owner of 8,133,333 shares of Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) common stock, including 2,000,000 shares issued to trusts held for benefit of his sons and 33,333 shares issuable upon the exercise of vested options. In addition, 2,000,000 of SPI options and restricted stock awards were substituted by awards of Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) restricted stock and options to purchase shares of Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) common stock at $1.00 per share with the options having a term of five years and the restricted stock awards vesting over a period of three years.

As a result of the substitution, the Reporting Person was granted an option to purchase 100,000 shares of Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) common stock. The options are exercisable at $1.00 per share, will vest over a period of 3 years and have a term of 5 years. In addition, the Reporting Person also received substituted performance-based options to purchase 100,000 shares of Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) common stock, which options will vest at either 0% or 100%, such vesting to be determined on December 31, 2010 (the “Determination Time”). The vesting determination will be based on certain annual revenue performance goals of the Company. The performance goals will be determined on a cumulative basis at the Determination Time, to account for any year-to-year discrepancies in meeting each annual performance goal. On February 15, 2007, Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) re-domiciled in California by merging into its wholly-owned subsidiary, SPI. Through this merger SPI became the Issuer.

The Merger Agreement, as amended, was attached as Exhibits 10.1 to the Issuer’s Forms 8-K filed on August 29, October 10, December 6 and December 22, 2006, and is incorporated herein by reference.

On December 24, 2007, the irrevocable trusts established for the benefit of each Mr. Kircher’s two sons each purchased 20,000 shares of Issuer’s common stock. On December 31, 2007, the irrevocable trust established for the benefit of Mr. Kircher’s son, Scott Kircher, purchased 25,000 shares of the Issuer’s common stock.

Item 4. Purpose of the Transaction.

The Reporting Person acquired the Shares (described in Item 3 above) for investment purposes in connection with the Merger pursuant to the Merger Agreement.

In anticipation of the Merger described in Item 3, prior to the Merger Mr. Kircher was appointed as a director and as Chairman of the Board of the Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) effective as of September 5, 2006, to fill an existing vacancy. Effective upon the Merger, pursuant to the Merger Agreement Mr. Kircher remained a director of the Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) and was appointed as the Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) Chief Executive Officer while the remainder of the Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) directors and officers resigned their positions. Concurrently, to fill vacancies created by such resignations, the current officers and directors of SPI were appointed to the same respective positions of Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc. and together with the Reporting Person assumed management control of the Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.). Although there is no present intention to change the Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) number of authorized directors, the Reporting Person reserves the right, along with the other directors, to identify and appoint such qualified candidate(s) to the Solar Power, Inc’s., a Nevada corporation (formerly Welund Fund, Inc.) Board of Directors, as may be deemed appropriate now or in the future.

In addition, as a condition to the Merger, Welund Fund, Inc. changed its corporate name to Solar Power, Inc., a Nevada corporation. Effective October 5, 2006 the Solar Power, Inc., a Nevada corporation filed a certificate of amendment with the Nevada Secretary of State effecting the name change. Furthermore, as a result of the Merger, the Solar Power, Inc., a Nevada corporation discontinued its business relating to the pool of finance receivables and commenced its new business and operations in the solar power business.

Additionally, on February 15, 2007, Solar Power, Inc., a Nevada corporation (formerly Welund Fund, Inc.) re-domiciled in California by merging into its wholly-owned subsidiary, Solar Power, Inc., a California corporation. As a result, Solar Power, Inc., a California corporation became the Issuer.
